What Is Microsoft Teredo Tunneling Adapter
In a word, it is software that enables your PC to work with both IPv4 and IPv6. This adapter can act as a translator to interpret these two different IP address schemas, making you access the website you want no matter your PC has an IPv4 or IPv6 address.
Now, let’s see a simple explanation.
IPv4 (with the format similar to 192.168.1.1), an IP protocol, assigns a computer with a unique address. It is an identity that can be used to communicate with the world over the Internet. Most persons are on the IPv4 technology.
However, as there are more and more persons and less and less available IPv4 addresses, IPv6, Internet Protocol Version 6 (with the format similar to 2001:DB8:0:0:8:0:417A) appears. It brings an uncountable number of addresses.
When a computer is only using IPV4, the Internet connection runs smoothly. But with IPv6 added in, the network connection problem appears. To get rid of this situation, Teredo Tunneling appears. As a translator, it translates IPv4 to IPv6 and vice-versa.
