What is Microsoft Teredo Tunneling Adapter and How to Install and Solve Issues? [Fixed]

Microsoft Teredo Tunneling Adapter is a technology that aids in computer networking. It helps the IPv-6 capable hosts that do not have native IPv-6 connection but instead present in IPv-4 internet. This is done by providing full IPv-6 connectivity to the IPv-6 capable hosts. It might be confusing for many who are not familiar with fancy terms such as IPv-4 and IPv-6. In this post, we will explain in simple terms all about this transition technology. In addition, you will learn how to install this application in your PC.

IPv-4 and IPv-6

Internet is nothing but connection of networks all over the world. Each connection has a unique address by which it is identified. This unique address is given by the IP Protocol called IPv-4. However, the increase in internet usage has resulted in the scarcity of IP addresses. Many people are using the internet nowadays due to technological advancements. As a solution to this issue, IPv-6 was introduced. This Internet protocol version 6 is capable of providing innumerable addresses. Hence, it solves the problem of IP address shortage.

What is the role of Microsoft Teredo Tunneling Adapter?

IPv-6 has resolved the issue with assigning new IP addresses to networks. However, it poses a problem, which is that network connectivity. Network with IPv-4 has to connect with IPv-6. For this, we need some transition technology, which can interpret the different languages of IPv-4 and IPv-6. This technology is nothing but Microsoft Teredo Tunneling Adapter.

How does it work?

The adapter works by identifying the type of NAT present in an IPv-4 network. Then it actually gives the host using the adapter a unique IPv6 address. This address can be used globally for routing purposes. To transmit the IPv6 packets to IPv4 network, it encapsulates them in UDPv4 datagrams. It is an interesting process and if you want to install this adapter continue reading the post.
