Teredo [3] is a stateless mechanism to encapsulate IPv6 traffic in IPv4 when there is an IPv4 NAT between the tunnel endpoints. This document enhances Teredo by providing a stateful IPv6 in IPv4 connexion which enables additional features to be used, like permanent IPv6 address or prefixes. It uses the Tunnel Setup Protocol (TSP) [2] to negociate the parameters of the tunnel and identify the NAT translation map. TSP also enables negociation and establishment of prefixes, routing, DNS delegation and other parameters related to the tunnel.
