Teredo Overview
Overview Teredo, also known as IPv4 network address translator (NAT) traversal for IPv6, is an IPv6 transition technology that provides address assignment and host-to-host automatic tunneling for unicast IPv6 connectivity when IPv6/IPv4 hosts are located behind one or multiple IPv4 NATs. To traverse IPv4 NATs, IPv6 packets are sent as IPv4-based User Datagram Protocol (UDP) messages. This paper provides an overview of Teredo - including Teredo addresses and packet structures - and detailed explanations of how communication is initiated between Teredo clients, Teredo host-specific relays, and IPv6-only hosts using the IPv4 Internet, the IPv6 Internet, Teredo servers, and Teredo relays.
