How to Install Microsoft Teredo Tunneling Adapter

Microsoft Teredo Tunneling Adapter is a virtual device acting as a network translator between IPv4 and IPv6. Without direct (native) access to IPv6 networks, most PCs are now linked to the Internet via IPv4 connections. This difficulty might be solved using this adapter technology, which allows an IPv4 network to communicate with an IPv6 network and vice versa.

How to Install Microsoft Teredo Tunneling Adapter

To comprehend what a Teredo adapter is, you must first understand what IPv4 and IPv6 are. IPv4 is an Internet Protocol that assigns each of our computers a unique address that you use to communicate with the rest of the world. IPv4 is still extensively used, but now that there are two, a person speaking in one will be understood by the other, not by those speaking in the other. As a result, making networks communicate with one another will be difficult since the Internet is all about connecting and interacting with one another. As a result, we require an interpreter to convert IPv4 to IPv6 and vice versa, which is what Teredo Tunneling provides.

Method 1: Through Device Manager

This section will show you how to install the Microsoft Teredo Tunneling Adapter on Windows 10. The adapter is available for download on the Internet. Follow the below steps:

Note: Ensure that your Internet connection is operational.

1. Press the Windows Key, type Device Manager and hit the Enter key.

2. Double-click on Network adapters to expand it.
