How to Install and Enable Microsoft Teredo Tunneling Adapter in Windows 7?

Updated on September 1, 2017

If you want to install Microsoft’s Teredo Tunneling Adapter on Windows 7, then it’s better to understand what IPv4 and IPv6 are. We already know IPv4 is an Internet Protocol version 4 that we were using for decades to access internet. It was an identity for every computer in the internet and they all were speaking only IPv4 language. Everything was well until the Internet ran out of enough IP addresses and we badly needed another protocol that can provide huge IP address range. Thus IPv6 born, the new language that every IPv6 computer will speak. Now the problem started (well, IPv6 came in to rescue us from the problem of IP address depletion isn’t?) – still many websites and networks around the world are yet to implement IPv6. It means, they are all still working on IPv4 protocol. Now there are computers speaking two different languages – IPv4 and IPv6. How to make them communicate each other? Well, we use Teredo Tunneling for that. Teredo Tunneling is an language translator (not really), that translates IPv4 to IPv6 and IPv6 to IPv4.
