Connection via IPv6 protocol Rostelecom. IPv6 protocol: configuration on Windows systems. What does IPv6 without network access mean?

Hardware

Probably, many users of computer systems, delving into network settings, noticed that in the list of protocols, in addition to the well-known IPv4, there is also a sixth version (IPv6). Setting up this protocol and everything connected with it will now be discussed in the review.

TCP/IPv6: what is it?

Actually, in simple terms, the sixth version of the protocol is simply the successor to the fourth version of IPv4, which was developed back in the 70s of the last century. Like its predecessor, the IPv6 protocol is responsible for network identification of computer terminals by assigning each of them a unique external address.

As for the differences, IPv6 is capable of generating a much larger number of unique addresses and, unlike the fourth version, which, even by the most conservative estimates, no longer copes with its direct function, uses a 128-bit combination rather than the outdated 32-bit standard . It is not difficult to guess that the number of generated addresses is increasing simply incredibly. Among other things, the level of connection security here is an order of magnitude higher, at least.

Setting up IPv6 (Windows 7 and higher)

But it was all theory. Let’s move on to practice and see how IPv6 Windows systems are configured, starting with “seven”. Windows XP, due to its declining relevance, will not be considered. Yes, and setting protocol parameters in it is somewhat more complicated.

But the so-called boxed versions of Windows 7 and higher systems are ready to use the sixth version of the TCP/IP Internet protocol immediately after installation. By and large, the user does not need to configure anything special. The main thing is to just enable the protocol itself.

Another thing is that the problem may lie with the provider's service. It either supports IPv6 or it doesn't. As a rule, large companies providing Internet connection services have an active DHCP server at their disposal. IPv6 (the setting will be presented below) in this case will be activated automatically by the provider.

Now another important point. Here you need to pay special attention to the connection itself, which is supposed to use the IPv6 protocol. The setup, if the user’s connection is via a wireless router, only involves activating it exclusively towards the provider, and specifically on the router, which will be discussed below. But the network parameters make no sense in using it.

So, the provider has an active DHCPv6 server. The user is wondering about activating the IPv6 protocol. The setup initially involves entering the network connections section. You can do this in the simplest way using the ncpa.cpl command, entered in the “Run” menu. Right-click on the adapter to open the menu and select the properties menu. In the new window, on the network tab, make sure that the protocol is checked, that is, its use is enabled.

Now we enter the properties of the IPv6 protocol. In the new window, as a rule, automatic parameters for obtaining an IP address and DNS server should be specified.

If automatic assignment of basic values is not provided, you need to find out the data from the provider and then enter it in the appropriate fields. For example, IP can be left in automatic assignment mode, and for DNS servers use combinations of the format XXXX:XXXX:XXXX::XXXX (or vice versa, use the desired IP and leave DNS in automatic mode). At the same time, you can also configure servers according to recommendations, for example, of some common services such as Google, Yandex, etc. Such settings can be found on the Internet.

Checking the settings are correct

Now you need to make sure that the protocol is enabled and working. To do this, right-click on the network connection icon in the system tray and select the status bar, then click the details button.

If the new window contains the IPv6 value, everything is fine. In addition, today you can find quite a lot of specialized resources on the Internet that allow you to test the use of the IPv6 protocol online. There is no point in citing them all. Just search for the same Google and Yandex services.

IPv6 (Zyxel): setting up the protocol on routers

Finally, a few words about setting up the protocol on the router. For example, let's take the Zyxel models. You need to make sure in advance that the router has firmware version no lower than 2.00. To begin, we enter the router menu through the address bar of the browser (192.168.1.1) and use the login admin and password 1234.

In the settings you need to check the box next to the IPv6 protocol. Configuration is done by creating a new connection with automatic receipt of parameters (ideally, of course) or using special clients like web configurators or tunnel brokers. If this option does not work, you will have to use special commands and set the settings from the command line. Due to the complexity for the average user, the methodology is not given. But. If anyone has a desire, a complete list of commands can be found on the same Internet.

Conclusion

As you can see, setting up the IPv6 protocol is completely simple to both activate and configure. The most important condition here is support from the provider. Everything else is automated to the limit, so on Windows 7 and higher systems you can just enable the protocol and immediately start using it for an Internet connection.

IPv6: definition, activation and configuration

In Windows operating systems, access to the World Wide Web is carried out using the TCP/IP protocol, the principle of which is carried out by allocating an IP address to each computer, which is unique for each terminal. However, many novice users turn to the Ipv6 protocol. What is this technology and what are the main differences between it and IPv4, and what prospects does it have in the near future? Definition of IPv6

Without going into technological details, Ipv6 is a more modern and modernized version of Ipv4, which was born back in the late 70s. It is based on identical working algorithms embedded in its brother. The main difference is the IP distribution system and a more reliable security system.

Most users do not encounter IP addresses when browsing the Internet, since the connection process is carried out using domains, also called DNS. However, to better understand the design and underlying factors of this technology, it is necessary to take a closer look at how this protocol works.

Historical facts When modern Internet technologies were just beginning to develop and the World Wide Web was just being created, a special technology for recognizing computers on the network was developed, which provided easier and faster access to the Internet. According to the theory behind this technology, each terminal had to have a unique IP address, which would be different for each machine.

The operating principle of this technology was based on the routing and transmission of data arrays via the Internet or multiple local networks interconnected through servers or separate systems. For a more clear example of this, we can cite the functioning of e-mail, in which each letter has its own addressee. Thus, if several machines have the same IP address, such sending will simply become impossible, and the letter will be simultaneously received by several users with the same addresses. At that time, mail servers did not yet exist, and everything worked using the POP3 and SMTP protocols. At that time, the IPv4 protocol was born, the operating principle of which was based on the creation of a thirty-two-bit, four-digit personal address. From the above it follows that more than four billion different IP addresses were created simultaneously.

Today, this approach has completely become obsolete, since new addresses simply cannot be created anymore. If you believe some IT specialists, the end of the era of this protocol took place back in 2009. It was then that engineers began to think about possible solutions to the problem. Thus, the Ipv6 protocol appeared, which in fact is not an innovative development, but is only a modernized version of Ipv4. It is worth noting that development was also carried out on an alternative technology, which even received its unique name - ST, and was later renamed Ipv5. However, it was never able to find application in practice and was later completely forgotten. Therefore, today IPv6 is considered the most modern standard, behind which lies the future.

IPv4 VS Ipv6: main differences

Let's look at the main differences between these two standards. The main one is the length, which in the new standard is 128 bits instead of the thirty-two that were implemented in the outdated technology. Thus, the increased length allowed the generation of an infinite number of new unique IP addresses.

In addition, the outdated technology also had a significant number of various problems that negatively affected the stability of operation. Among them are the speed of data transfer, as well as the low level of protection of confidential user information. When creating a more modern protocol, which later became Ipv6, all problems and shortcomings were completely eliminated, however, this did not bring much popularity to the new technology even despite the fact that it is implemented in modern versions of operating systems. Despite implementation, it remains unused by default. Moreover, not all companies providing network access services support this technology at the proper level. If there is none at all, the user will receive a system notification that the IPv6 protocol is enabled without an Internet connection.

Activating the IPv6 protocol in modern versions of Windows

Microsoft has implemented support for Ipv6 technology in its operating systems from version seven and higher, so we will look at the process of enabling this protocol using these particular Windows as an example. It’s worth noting right away that if your computer is connected to the local network via a wireless router, then there is no point in activating and configuring the protocol, since no effect will follow. But if you use a direct wired connection, then this is very important.

The first step is to find out whether this technology is activated in Windows. To do this, open the command window and run the ipconfig command. If there is no mention of this technology on the screen, then it is deactivated and needs to be started manually. To activate it, you need to go to network connections, and then open the “Properties” of the required network adapter. In the window that opens, check the Ipv6 protocol box and configure it, which we will talk about a little later. Activating IPv6 in Windows XP

If everything is clear with modern versions of the OS, then how to activate the Ipv6 protocol in outdated XP? You can enable this technology in the same way through the properties of network connections, however, it is much easier to do this through the command line using a specific set of commands. To do this, you need to run the commands one by one: Netsh, Interface, ipv6 and install. If this procedure seems too complicated to you, then the IPv6 protocol is activated through the properties of network connections in a similar way to the method described above.

Setting up IPv6 automatically

So, you have enabled the IPv6 protocol, what to do next? Now you need to configure it, however, this is only relevant if the provider supports the above technology. Most often, to configure IPv6 there is no need to manually enter IP addresses. In most cases, companies providing Internet access use DHCPv6 servers that use dynamic IPs. In simple terms, each computer is allocated a temporary individual address, which is valid only for the duration of one session. For subsequent connections, a new IP address will be allocated.

Thus, to configure Ipv6 you just need to check the boxes next to the items for automatically obtaining IP addresses and DNS addresses. If automatic configuration is not possible for some reason, but the operating system supports IPv6, then the IP will be assigned automatically, and the DNS server address will need to be registered independently.

Alternative Setup Methods

If you have enabled Ipv6 support in Windows, but find that automatic configuration is not possible, then do not despair, as there are alternative configuration methods.

There is nothing complicated about this, the main thing is to specify the correct values for the primary and secondary DNS addresses. For stable operation of the protocol, it will be enough to register 2001:4860:4860::8888 as the main DNS server address and 2001:4860:4860::8844 as an additional one. The proxy server parameters can be left blank, since it is not used in most addresses of computers that are part of local networks.

It’s worth noting right away that the IP addresses required to work with Google and Yandex services will differ, however, this does not make a fundamental difference. However, in order not to experience any special problems when accessing the network, it is recommended to clarify the parameters of an alternative option for setting up the Ipv6 protocol with your provider; however, in most cases this is not required, since the setup takes place automatically without any problems.

Functionality check

Let's assume that you have already activated and configured the IPv6 protocol, what should you do next? Now you need to run a performance check to make sure everything was done correctly. This can be done using the ipconfig command, which should be run through the command line. If no errors were made during the startup and configuration process, then IPv6 will be displayed on the monitor display. To obtain information about the IP addresses used by the computer, you need to view data on the status of the network connection. This can be done simply by clicking on the corresponding icon located in the tray near the system time.

Conclusion

So, our article has come to its logical conclusion. In it, we examined the main aspects that relate to the modern Internet protocol Ipv6, namely its activation and configuration. As you have probably already seen, there is nothing complicated about this, and the process itself occurs in a similar way for different versions of Windows OS. Finally, it is worth noting that this technology is the future, since every day the number of modern gadgets is only increasing and they all support this technology.

Setting up IPv6 in Windows 8.1

1. Setting up the service

First we need to enable the "IP Auxiliary Service" service (if it is disabled)

My computer (context menu) –> Management -> Services Look for the “IP Auxiliary Service”, call the properties, set the startup type to “Automatic”, and Run:

2. We set the DNS servers

set the DNS server Google DNS IPv6

2001:4860:4860::8888 2001:4860:4860::8844

Without setting up DNSv6, you will not be able to open websites in your browser using their domain name. We do not touch the IPv4 settings.
3. Installing and Configuring Teredo Launch the “Local Group Policy Editor”

Run - gpedit.msc

Administrative Templates -> Network -> TCP/IP Settings -> IPv6 Tunneling Technologies Default Teredo Classification -> Enable -> Enabled State Teredo Update Rate -> Enable -> 30 Teredo State -> Enable -> Enterprise Client Teredo Client Port -> Not specified Server name Teredo –> Enable –> Select from the list: teredo.remlab.net (France) teredo.trex.fi (Finland) teredo.ipv6.microsoft.com (United Kingdom / USA) default for windows teredo.ngix. ne.kr (South Korea) teredo.managemydedi.com (USA, Chicago)

Teredo.autotrans.consulintel.com (Spain)

For reliable and fast work, I advise: teredo.remlab.net or teredo.trex.fi But it’s better to check the availability of all servers yourself, via ping teredo.remlab.net Servers from Microsoft work and are located in different parts of the planet, which one happens to you is pure chance !
Let's move on. For more productive operation of IPv6, we completely disable other tunneling technologies:

Repeater name 6to4 -> Disable

6to4 Relay Name Resolution Interval -> Disable 6to4 State -> ENABLE -> Disabled State IP-HTTPS State -> Disable ISATAP Router Name -> Disable ISATAP State -> ENABLE -> Disabled State

That's all!

Use the service to check.

http://test-ipv6.com/

The service was created specifically for those who are struggling with setting up IPv6; it will tell you about all the problems, conduct a sufficient number of tests, and at the same time show your IPv6 address.

IPv6 - what is it? How to enable iPv6?

As you know, in computer systems with Windows OS on board, the TCP/IP protocol system is used to access the Internet, which provides for assigning each terminal a certain unique IP address, which is not repeated on any machine (meaning external IP). But today many are increasingly looking towards the IPv6 protocol. What it is, how to enable and configure it, will be discussed now. In addition, it will be possible to see the significant difference between IPv4 and IPv6, as well as find out the prospects for introducing new technology in the near future.

IPv6: what is it?

In simple terms, IPv6 is an improved version of the IPv4 protocol, which was developed back in the 70s of the last century.

In principle, in terms of the basic algorithms embedded in the IPv6 operating system, this protocol is almost identical to the original approach. The only difference is in the assignment and distribution of addresses to computer terminals and the security system.

An ordinary user, when using Internet access, in most cases practically does not encounter IP addresses, since the so-called domain name system, abbreviated as DNS, is responsible for all connection establishment procedures. However, in order to better understand the topic: “IPv6: what is it?”, You should understand a little about the basic principles of the functioning of this protocol.

A little history

At the dawn of the development of Internet technologies, a special method for identifying computer terminals was developed for quick and convenient access to the World Wide Web. As was then assumed, each machine should have a unique identifier, and one that would not be repeated even once.

The purpose of this approach was to route and transmit data on the Web or interconnected networks between servers and individual computers (for example, email). Agree, after all, a letter or message should be sent to a specific addressee. And with two or more identical IP addresses of terminals, delivery can be made to anyone. At that time there were no official mail servers, but POP3 and SMTP protocols were used.

It was in those years that the IPv4 protocol was developed, which involved the creation of a unique address in the form of four numbers of 8 bits each, which gave a total of 32 bits. Thus, we were talking about creating about four billion never repeated addresses.

Today the situation has changed, and, as it turns out, the IPv4 protocol is no longer able to generate new addresses. Some experts argue that it had exhausted its capabilities by 2009. It was then that many scientific minds began to think about how to expand the basic parameters. In fact, these developments in the form of an additional add-on for IPv4 were started back in the late 70s and then received the name ST protocol, then ST2, and a little later - the unofficial name IPv5. But this development never caught on, and was not even adopted in terms of long-term development. Today it is believed that the newest and most popular protocol will soon be IPv6.

Difference between IPv4 and IPv6 protocols

Now let's look at the main differences between these two systems. The most important thing is that the length of any IP address is 128 bits. Accordingly, the number of newly created unique identifiers can be increased almost indefinitely.

At the same time, IPv4 has many serious security problems in terms of data encryption, as well as bandwidth. In addition, in this system, during the same transfer of information, quite strong delays are observed, which negatively affects the operation of some network applications.

When developing IPv6, all this was taken into account, but the protocol itself has not yet been widely implemented, although it is present in the latest operating systems, it is not enabled by default. In addition, not all providers support Internet access at this level. It's good if there is such support. Otherwise, even after correct configuration in automatic mode, the user will receive a message that IPv6 is being used without access to the network. However, even if this protocol is not yet used, the main points of its inclusion and configuration still need to be considered.

How to enable IPv6 in Windows 7 and higher

So, first, let's look at systems like the "seven" and higher. Let's make a reservation right away: if, for example, you use a router (wireless router) at home, there is no point in configuring IPv6 to work on a local network, except perhaps only in the direction of the provider. But if the cable is connected directly, then yes.

First, you should check whether the protocol is enabled on the system. This can be done quite simply by entering the ipconfig command in the command line (call via cmd in the Run menu or the combination Win + R). If there is no mention of IPv6 on the screen, you will have to enable the protocol manually.

How to enable IPv6? Yes, it’s easy to use the network connections section in the standard “Control Panel,” but it’s easier to enter the ncpa.cpl command in the same “Run” menu.

Now select the adapter network and enter its properties. Here you should check the box next to the protocol name, and then configure it (this will be discussed separately).

Enable IPv6 in Windows XP

Now let's look at the XP version of Windows. In principle, IPv6 can also be enabled in this system through the properties of network connections in the Control Panel, but it is easier to do this from the command line, where the following commands are written sequentially:

Netsh (+ input),

Interface (+ input),

IPv6 (+ input),

Install (+ input).

Enabling the protocol from the “Control Panel” is identical to the case described above.

Automatic setup

Now let's look at the IPv6 configuration. The Internet connection will only benefit from this (again, the setting is only relevant if the provider supports this protocol).

In most cases, to correctly configure the IPv6 address received by the computer terminal, you do not need to manually enter it. This is due to the fact that almost all large provider companies have an active DHCPv6 server in their own network, from which, in fact, IP is assigned, that is, the server itself issues an IPv6 address to a specific machine.

Thus, for the simplest setup, you should use the fields for automatically obtaining the IP address and DNS server address. If automatic configuration is not possible, but IPv6 is supported, the IP address can be obtained automatically, but the values for the preferred DNS server will have to be entered manually. And there are some snags here.

How to enable IPv6 is probably already clear. Now a few words directly about setting up an alternative configuration.

As mentioned above, the main role here is to set the correct values for the preferred and alternative DNS server. For practical use, the following data should be entered (for example, for Google services):

The preferred DNS is 2001:4860:4860::8888.

Alternate DNS - 2001:4860:4860::8844.

Proxy settings can be left unchanged. In most cases, a proxy server is not used for local addresses.

It goes without saying that you can use, say, addresses for Yandex services, etc. This does not play a special role in this case. However, it is best, if possible, to find out the parameters of an alternative configuration from the provider. As they say, it will be more reliable. However, as practice shows, in most cases automatic settings work just fine.

Checking work

So, IPv6 has been enabled and configured. Now all that remains is to make sure that the protocol is actually enabled and works without problems.

To check the connection we use the same ipconfig command. After all correctly performed procedures and settings, the protocol should be displayed on the screen. If you set out to view the address, you can simply click on the network connection icon in the system tray and select the status menu. The same can be done from the “Control Panel”, where you select the appropriate section of network connections and then go to the active connection.

Instead of an afterword

That, in a nutshell, is all about the IPv6 protocol. What this is, I think, is already a little clear. As you can see, the settings, in general, are not as complicated as it might seem at first glance. All of them are available in the corresponding sections in the “Control Panel”. True, in XP it is better to use the command line.

According to most experts, in the coming years there will be a complete transition to a new type of protocol, since it has quite great prospects, as well as a more advanced operating system. After all, if you look, the matter is no longer limited to computers alone. What does the incredibly increased amount of mobile equipment consist of, but in order to access the Internet, each such device is also assigned a unique identifier. So IPv4 simply cannot cope with such an impossible task.

It is believed that in the near future the use of mobile gadgets will increase even more. Well, the new address distribution system based on the IPv6 protocol will help to cope with this situation. It is the future, especially since, due to the increasing number of devices that require connection to the World Wide Web, almost exponentially, the new protocol has much more capabilities for providing addresses, and even greater bandwidth.

Teredo is a network protocol designed for transmitting IPv6 packets over IPv4 networks, in particular through devices operating using NAT technology, by encapsulating them in UDP datagrams. In short, a useful feature if the site (host) has only an IPv6 address, but you need to go to it.

There are two ways, fast (always helped me) and not fast at all:

1. Use a ready-made batch file - TEREDO-WIN7.bat (zip) (run as Administrator!), written for the average user of the Russian version of Windows 7/8, then check the functionality on test-ipv6.com

Pause reg add HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\Dnscache\Parameters /v AddrConfigControl /t REG_DWORD /d 0 timeout /T 3 sc config iphlpsvc start= auto net start iphlpsvc timeout /T 10 netsh interface ipv6 reset timeout /T 3 netsh interface ipv6 set dns “Local Area Connection” static 2001:4860:4860::8888 primary validate= no netsh interface isatap set state disabled netsh interface 6to4 set state disabled netsh interface teredo set state type=enterpriseclient servername=teredo.trex.fi refreshinterval =default clientport=default

timeout /T 3 netsh int ipv6 delete route::/0 Teredo netsh int ipv6 add route::/0 Teredo

timeout /T 3 ipconfig /flushdns Pause

Reboot if it doesn't work right away

2. Or make the necessary settings yourself:

Step I. Remove unnecessary ones My Computer (context menu) – Device Manager

View – Show hidden devices.

Feel free to delete only what is related to Teredo, ISATAP, 6to4 and IPHTTPS:

We check through the command line (start -> run -> cmd, or the key combination WIN + R) Using the ipconfig command:

Step II. Setting up the service First we need to enable the IP Auxiliary Service service (if it is disabled)

My computer (context menu) –> Management -> Services We look for “IP Auxiliary Service”, call the properties, set the startup type to “Automatic”, and enable:

Step III. Setting up local IPv6 (optional) Enter “Network connections” into the address bar of the explorer

Then you need to assign an explicit IPv6 address in the network settings - subnet mask: 48

Calculate your local IPv6 based on local IPv4 (exactly the one on the network card): http://wb0.ru/ipconv.php Enter your local IPv4 and take the value from “IPv6 (IPv6 to IPv4 routing)” (default is your external IP)

Example: 192.168.1.2 → 2002:c0a8:0102:: 172.16.0.2 → 2002:ac10:0002::

If you do not have a local IP (your OS immediately has an external IP), then converting local ipv4 to ipv6 is not required, because it does not exist. It is enough to enter only DNS addresses...

Often, explicit assignment of a local IPv6 address in the Teredo configuration is not required.

Step IV. Purpose of DNSv6 For this I can recommend using Google DNS IPv6

2001:4860:4860::8888 2001:4860:4860::8844 Without setting up DNSv6, you will not be able to open sites in the browser by their domain name.

We do not touch the IPv4 settings.

Step V. Installing and Configuring Teredo Launch the “Local Group Policy Editor”

Start – Run - gpedit.msc (Editions: Professional, Corporate, Ultimate)

(Installing gpedit.msc in Windows 7 Starter, Home edition)

Teredo server name –> Enable –> Select from the list:

Teredo.remlab.net (France) teredo.trex.fi (Finland) teredo.ipv6.microsoft.com (United Kingdom / USA) default for windows teredo.ngix.ne.kr (South Korea) teredo.managemydedi.com (USA , Chicago) teredo.autotrans.consulintel.com (Spain) For reliable and fast work, I recommend: teredo.remlab.net or teredo.trex.fi But it’s better to check the availability of all servers yourself, via ping teredo.remlab.net

Servers from Microsoft work and are located in different parts of the planet, which one you get is pure chance!

Let's move on. For more productive IPv6 operation, we disable other tunneling technologies completely: 6to4 relay name -> Disable 6to4 relay name resolution interval -> Disable 6to4 state -> ENABLE -> Disabled state IP-HTTPS state -> Disable ISATAP router name -> Disable

ISATAP State -> ENABLE -> Disabled State

Step VI. Setting up the interface/routes Start – Run – cmd (or the WIN+R key combination)

route print -6 And in the “Interface List” section, find out the Teredo interface (if there is none, reboot)

It remains to execute the last 2 commands

netsh int ipv6 delete route::/0 Teredo netsh int ipv6 add route::/0 Teredo wait a few seconds and check IPv6 functionality:

ping ipv6.nnm-club.me

In some cases, however, even after this Teredo remains inactive, then it must be forcibly activated: If external IPv4 is allocated dynamically, the last two commands will have to be repeated after each switch off/on of the router/modem or each time the address changes (usually once a day), What is the best way to create a batch file (*.bat):

timeout /T 15 netsh int ipv6 delete route::/0 Teredo timeout /T 3 netsh int ipv6 add route::/0 Teredo timeout /T 3 netsh int teredo set state type=enterpriseclient timeout /T 3 ipconfig /flushdns timeout /T 3 Why is this needed? - Your IPv6 (Teredo) address is strictly tied to your external IPv4 address; when you change, the connection is lost. Put this batch file into OS autostart.

For reasons that are not at all clear, it is necessary to change “Corporate Client” to a simple “Client” in the settings.

In fact, the operations performed may not give you a 100% guarantee that Teredo will work, this may be due to symmetric NAT (a very rare case)…

Step VII. Setting up the registry In order not to constantly reset the route

netsh int ipv6 delete route::/0 Teredo netsh int ipv6 add route::/0 Teredo In the registry at

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\Dnscache\Parameters

Create a DWORD key - AddrConfigControl equal to null.

To do this, you need to run the registry editor regedit (as administrator, WIN+R -> regedit). This edit in the registry saves us (with 99% probability) from 2 problems at once: - Registering local v6 addresses in “Step III. Setting up local IPv6”

Do “delete route” and “add route” at “Step VI. Setting up the interface/routes”

When changing your IPv4 address, don't panic if your IPv6 disappears. Teredo will update within 1-5 minutes.

When setting up Teredo or 6to4, the maximum score on test-ipv6.com 7/10 is normal.

If you follow these instructions correctly, setting up Teredo/IPv6 will be done one time, without further user intervention.

Disable Teredo/6to4/ISATAP at the root.

1. Launch “Local Group Policy Editor” Start – Run - gpedit.msc

2. Computer Configuration - Administrative Templates – Network – TCP/IP Settings – IPv6 Tunneling Technologies

Call the properties of each item “Set state XYZ” - enabled - disabled state. “enable disabled state” is nonsense, but it’s true

IP-HTTPS status is not set!

Roskomnadzor can successfully block services that use IPv4, so they are switching to parallel use of the IPv6 standard, addresses in which it is impossible to block. Effective bypass of blocking is possible using the IPv4 protocol, which was developed back in the 80s. This is due to the extremely limited number of available IP addresses. IPv6 provides many more addresses and is supported by many ISPs, but must be configured manually. The problem is that it is not activated on most devices. Fortunately, setting up IPv6 on a computer is not difficult.

Right-click on the Internet connection icon in the notification area on the taskbar, open Network and Internet settings.

Select "Configure adapter settings", right-click on the icon of the adapter you are using and click "Properties".

Check the box next to “IP version 6 (TCP/IPv6)”.

Now you need to get the IPv6 settings for the router and configure the router.

Go to the website ipv6.ip4market.ru, enter your email address (IPv6 settings will be sent there) and phone number (the left one is fine, but the real one is better).

Open the router settings in your browser (different routers have different control panel addresses) and install the component responsible for IPv6 operation, if it is not installed.

The IPv6 section will appear in the control panel menu. Click "Add Connection" (or something similar) and complete the settings that were emailed to you. Save them.

Keep in mind that for IPv6 to work, this protocol must be supported by your ISP (you can check this with technical support), as well as by your router and network adapter. You can check whether your computer is configured to use IPv6 on the website

According to the theory behind this technology, each terminal had to have a unique IP address, which would be different for each machine.

For a more clear example of this, we can cite the functioning of e-mail, in which each letter has its own addressee. Thus, if several machines have the same IP address, such sending will simply become impossible, and the letter will be simultaneously received by several users with the same addresses. At that time, mail servers did not yet exist, and everything worked using the POP3 and SMTP protocols.
At that time, the IPv4 protocol was born, the operating principle of which was based on the creation of a thirty-two-bit, four-digit personal address. From the above it follows that more than four billion different IP addresses were created simultaneously.

IPv4 VS Ipv6: main differences

In addition, the outdated technology also had a significant number of various problems that negatively affected the stability of operation. Among them are the speed of data transfer, as well as the low level of protection of confidential user information.
When creating a more modern protocol, which later became Ipv6, all problems and shortcomings were completely eliminated, however, this did not bring much popularity to the new technology even despite the fact that it is implemented in modern versions of operating systems. Despite implementation, it remains unused by default. Moreover, not all companies providing network access services support this technology at the proper level. If there is none at all, the user will receive a system notification that the IPv6 protocol is enabled without an Internet connection.

Activating the IPv6 protocol in modern versions of Windows

If everything is clear with modern versions of the OS, then how to activate the Ipv6 protocol in outdated XP? You can enable this technology in the same way through the properties of network connections, however, it is much easier to do this through the command line using a specific set of commands. To do this, you need to run the commands one by one: Netsh, Interface, ipv6 and install.
If this procedure seems too complicated to you, then the IPv6 protocol is activated through the properties of network connections in a similar way to the method described above.

Setting up IPv6 automatically

So, you have enabled the IPv6 protocol, what to do next? Now you need to configure it, however, this is only relevant if the provider supports the above technology.
Most often, to configure IPv6 there is no need to manually enter IP addresses. In most cases, companies providing Internet access use DHCPv6 servers that use dynamic IPs. In simple terms, each computer is allocated a temporary individual address, which is valid only for the duration of one session. For subsequent connections, a new IP address will be allocated.

Alternative Setup Methods

If you have enabled Ipv6 support in Windows, but find that automatic configuration is not possible, then do not despair, as there are alternative configuration methods.

Functionality check

Let's assume that you have already activated and configured the IPv6 protocol, what should you do next? Now you need to run a performance check to make sure everything was done correctly.
This can be done using the ipconfig command, which should be run through the command line. If no errors were made during the startup and configuration process, then IPv6 will be displayed on the monitor display. To obtain information about the IP addresses used by the computer, you need to view data on the status of the network connection. This can be done simply by clicking on the corresponding icon located in the tray near the system time.

Your ISP provides information about one of the following IPv6 Internet connection types: PPPoE, Dynamic IP (SLAAC/DHCPv6), Static IP, 6to4 tunnel, end-to-end (bridge).

1.Log into the router's web interface. If you don't know how to do this, please refer to the articles below:

2. Go to the section Additional settings (Advanced) > IPv6 .

3. Enable IPv6 and select the internet connection type provided by your ISP.

Advice:

If you do not know your Internet connection type, please contact your Internet Service Provider or an expert according to the already known information provided by your Internet Service Provider.

4. Fill in the information according to the requirements of different connection types. Red spaces must be filled.

1) Static IP address: Fill in the blanks and click Save ( Save).

2) Dynamic IP(SLAAC/DHCPv6): Click Advanced ( Advanced) to enter additional information if required by your provider. Click the Save button ( Save), and then -update( Renew).

3) PPPoE: By default, the router uses an IPv4 account to connect to the IPv6 server. Click More Settings ( Advanced) to enter additional information required by your ISP. Click the Save button ( SaveConnect).

Note:

If your ISP provides two separate accounts for IPv4 and IPv6 connections, clear the Use the same session with IPv4 connection check box and manually enter the username and password for the IPv6 connection.

4) 6to4 tunnel: Internet connection type IPv4 is a prerequisite for this type of connection. Click More Settings ( Advanced) to enter additional information if required by your ISP. Click the Save button ( Save) and click the Connect button ( Connect).

5) Pass-Through (Bridge): Click Save ( Save) and go to step 6.

5. Configuring LAN ports. Windows users are recommended to choose one of the first two types. Enter the address prefix provided by your ISP and click the Save button ( Save).

Users often notice the message “ipv6 without network access” in the “Status” window when connecting to the Internet. Let's figure out together why this happens, as well as how to fix the error on Windows 7, 8, 8.1 and 10.

IPv6 without network access when using a router

If the network cable is not connected directly to the PC’s network card, but goes through a router, then the absence of ipv6 is normal. Since the router uses the ipv4 protocol. Check the status of the ipv4 protocol, if there is no connection problem, no need to worry.

IPv6 without network access when connecting a cable to a PC network card

If the Internet cable is connected directly to the network card and the ipv6 protocol is inactive, configure the connection in the settings, provided that the ipv6 protocol is supported by your Internet provider.

Instructions:

Open network connections and select wired internet properties.
Select IP protocol version 6 from the list and open properties.
Use automatic data retrieval options. If you need to set specific values, check with your Internet service provider.
Save the applied changes.

Conclusion

If you notice the message “ipv6 without network access,” configure the protocol according to the instructions in the article, having first checked the necessary parameters with your provider. There is no need to panic about the ipv6 protocol not working if ipv4 is working properly. Because some operators do not support the ipv6 protocol, and the ipv6 protocol does not work when using a router.

Do you use the ipv6 protocol? What advantages have you noticed in comparison with ipv4? Write your opinion in the comments.
