5 Ways To Fix Microsoft Teredo Tunneling Adapter Missing Issue

The Microsoft teredo tunneling adapter is a software that allows the computer to run both the versions of Internet Protocols i.e. IPv4 and IPv6. It is basically a special adapter that helps to translate a domain name for IPv6. When this adapter malfunctions or is missing, then you can get various kinds of glitch information. There are a few reasons for this problem. Some of the usual causes are if the Windows Operating System is obsolete, then you can encounter this issue.

Further, if the Microsoft Teredo Tunneling adapter driver is corrupt due to some internal glitch, then there is a chance to get this error. Moreover, if the driver software of this adapter is not enabled, then this problem can crop up. This article will help you to eliminate all the problems within an hour.

Requirements for Microsoft Teredo Tunneling Adapter’s Smooth Functioning

As you know that the IPv4 uses 32-bit addresses, which means that it can support and assign up to 2^32 i.e. approximately four billion IP addresses to the devices. But, since due to the increase in the number of devices the unique IP address is going to end. So, there is a need to introduce a version of IP address which can accommodate more devices i.e. IPv6, once the existing set gets exhausted.

Now, the problem is that, since the computers are developed in such a way that they can understand the IPv4 addresses easily, but fails to do so when IPv6 addresses come along. This is the reason why the Teredo Tunnelling adapter is required. It is basically a translator that helps the machine to smoothly convert an IPv4 to IPv6 address and vice versa. This is done so that there is no communication problem between computers via the internet.

Methods to Fix Microsoft Teredo Tunneling Adapter Missing Problem Easily

In this section of the article, you will get various methods that will aid in resolving the Microsoft Teredo Tunneling adapter missing error effectively.
