The seventh version of Windows since its release has presented users with many surprises. So, many found in the system (more precisely, in the “Device Manager”) the driver for the Teredo tunnel adapter from Microsoft. What is this, not everyone understands. Therefore, it is worth focusing on what it is and how it all works. Separately, issues related to how expedient its use in computers in the post-Soviet space will be touched will be separately touched.
What is the Microsoft Teredo Tunnel Adapter?
Let's start with the very understanding of this term. Do not confuse VPN technologies, which involve the use of tunneling with data encryption and changing the IP starting point in the form of a computer terminal or mobile device from which an attempt is made to access a particular site, with the operation of Teredo.
To understand what the Microsoft Teredo tunnel adapter is, you need to bind together all the Internet access protocols used. Currently, Windows systems offer only two options: IPv4 and IPv6. The sixth version is not used in the post-Soviet space (with rare exceptions, since far from all providers and mobile operators have DHCPv6 servers at their disposal).
And the Microsoft Teredo tunnel adapter driver installed in the latest versions of Windows works like a converter. But the converter of what and into what? Next, see how it all works, and draw conclusions about whether to use this device or not.
How does the Teredo tunnel adapter work?
Western countries have gone ahead of us (this is not surprising). Many operators and providers of Internet access services, unlike ours, have refused to use the IPv4 protocol, which is not only morally outdated, but also cannot serve all the IP addresses available today, but gave its preference to its sixth version.
In this regard, Microsoft is ahead of everyone. However, as it turned out, when using the appropriate connection, the sixth and fourth versions of TCP / IP are incompatible with each other. Patching holes, Microsoft initially released updates, but it did not lead to anything. In the end, a virtual adapter appeared that was supposedly able to convert data from IPv6 to IPv4. But the developers did not stop there and included UDP protocols in support.
Adapter problems and simplest solutions
What is the Microsoft Teredo tunnel adapter as a virtual device, I think, is a little clear. Now consider a few issues related to constantly emerging issues.
This virtual device (it is not known for what reasons) is capable of causing a lot of errors (although some of them have no direct relationship to the adapter).
If such a problem arose and in the “Device Manager” the adapter was detected, but marked with a yellow marker, the easiest way to update or reinstall the driver. It does not make sense to turn to third-party resources, since this device is precisely the development of Microsoft, and Windows, even if you remove the device from the system upon reboot, whether you want it or not, will still install new drivers from its database. If you have an active internet connection, this is only welcome.
On the other hand, if you are not using an adapter, you can set a ban on connecting to it via the command line, as shown above. These commands deactivate not only the adapter itself, but also everything connected with it (not without reason the whole package is called Pseudo Interface). Have you noticed? Precisely "pseudo"! This has nothing to do with the real state of affairs.
How appropriate is the use of Teredo?
If you approach the Windows-systems containing such a tool, from a practical point of view, its presence in OS versions that are designed for use in the former USSR is completely unjustified.
Well, yes, maybe in a couple of years we’ll get to this. But then what? The same experts will release the seventh or eighth version of the protocol, which after the sixth will not be supported, although it is predicted for several more decades.
Instead of a total
That, in fact, is all about the question of what the Microsoft Teredo tunnel adapter is. As a result, it is worth noting that specialized terms and methods for introducing such technologies into computer systems were not considered here, but only general ideas about what it is and how it works are given. Of course, in fact, everything is much more complicated, but, in principle, with the simplicity of practical use, in principle, you do not even need to.
To disable it, one might be advised to turn to the services section or to the system registry, but for an ordinary user who is not familiar with the intricacies of performing such actions, that is enough. Although ... Even if you find Teredo in the registry and delete all the keys, the system will still restore them upon restart. To completely remove this driver and the device itself, you can use uninstaller programs like iObit Uninstaller, which uninstall even your own Windows system applets that cannot be uninstalled using standard methods.
