Teredo: Tunneling IPv6 over UDP through Network Address Translations
RFC 4380, “Teredo: Tunneling IPv6 over UDP through Network Address Translations”, is a Proposed Standard document published in February 2006 by C. Huitema. It has since been updated by RFC 5991, RFC 6081, RFC 9601. The canonical text is published by the RFC Editor.
Abstract
We propose here a service that enables nodes located behind one or more IPv4 Network Address Translations (NATs) to obtain IPv6 connectivity by tunneling packets over UDP; we call this the Teredo service. Running the service requires the help of "Teredo servers" and "Teredo relays". The Teredo servers are stateless, and only have to manage a small fraction of the traffic between Teredo clients; the Teredo relays act as IPv6 routers between the Teredo service and the "native" IPv6 Internet. The relays can also provide interoperability with hosts using other transition mechanisms such as "6to4". [STANDARDS-TRACK]
What “Proposed Standard” means
An entry-level standards-track specification: stable, peer-reviewed and a solid basis for implementation, though it may still evolve before becoming an Internet Standard.
