What Is Teredo Tunneling Pseudo Interface ^new^ Here

However, if your company security policy prohibits tunneling protocols, or if you are absolutely certain you have full native IPv6 connectivity and the adapter is causing specific errors, you can disable it.

While it often appears as a driver in your Device Manager, it isn't a physical piece of hardware; rather, it is a software-based "pseudo-interface" that acts as a bridge during the global transition between internet protocols. How Teredo Tunneling Works what is teredo tunneling pseudo interface

In most cases, Windows is smart enough to prioritize native IPv6 or IPv4 connections over the Teredo tunnel. It is a "backup" method of connectivity. However, if your company security policy prohibits tunneling

: It specifically allows these packets to pass through Network Address Translation (NAT) devices, like your home router, which usually block IPv6 traffic. It is a "backup" method of connectivity

: It wraps (encapsulates) IPv6 data packets inside standard IPv4 UDP packets.

The internet is currently transitioning from IPv4 (which has a limited number of addresses) to IPv6 (which offers nearly infinite addresses). However, many home routers and internet service providers (ISPs) still only support IPv4. Teredo solves this by "tunneling" traffic:

Teredo uses a technique called to transport data. Since most home routers use Network Address Translation (NAT) , which often blocks direct IPv6 traffic, Teredo overcomes this by:
