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]
