Running into issues with the Teredo Adapter on a Windows 10 device isn’t exactly an isolated case. There have been several instances of the above, thereby hampering the Internet experience for many.
However, no matter how intimidating the term might sound, we mentioned here in easy steps how to download and install the Teredo Adapter.
What is a Teredo adapter?
To begin with, the Teredo Adapter works to redress a key shortcoming that again can be attributed to the rapid proliferation of the Internet; the shortage of IPv4 addressing scheme.
Let’s understand it in simple terms. Since the Internet has exponentially grown off late, there simply aren’t many IPv4 addresses left to assign to new users. It is here that the IPv6 protocol comes into the picture, which opens up an almost infinite number of addresses to use.
However, since most of us all over the world continue to be reliant on IPv4 technology, this opens up the need to have a system that maps between IPv4 and IPv6 protocols. And that’s precisely what the Teredo Adapter from our topic today does.
Its primary job is to provide IPv6 functionality (the host’s compatibility with IPv6 is a must) to a device currently on an IPv4 connection.
Why Teredo Tunneling Adapter is not in legacy hardware section?
This issue occurs mostly if you’re missing certain registry entries. If this happens, the Teredo Tunneling Pseudo-Interface will be missing.
Another cause can be your drivers, so it’s not uncommon to see that Microsoft Teredo Tunneling Adapter has a driver problem.
Issues such as these will lead to Teredo is unable to qualify and many other errors, but luckily, there are ways to fix them.
