What is a common use case for Teredo?

Explanation:
Teredo is a tunneling mechanism that carries IPv6 traffic over IPv4 networks by encapsulating IPv6 datagrams in UDP packets. This is especially useful for devices behind NATs that don’t have a direct IPv6 path, because the UDP encapsulation can traverse those NATs and reach IPv6 hosts on the Internet via a Teredo server and relay. In short, it provides IPv6 connectivity across NATs without requiring native IPv6 everywhere. It isn’t about replacing IPv4 entirely, it doesn’t swap UDP for TCP for IPv6, and it isn’t a solution for multicast routing in IPv6-only networks.
