How to Download Teredo Tunnelling Adapter for Windows 10

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.
