The IESG has approved the Internet-Draft 'Transition Mechanisms for
IPv6 Hosts and Routers' <draft-ietf-ngtrans-mech-06.txt> as a Proposed
Standard. This document is the product of the Next Generation
Transition Working Group. The IESG contact persons are Bert Wijnen and
Randy Bush.
Technical Summary
This document specifies IPv4 compatibility and transition mechanisms
which include providing complete implementations of both versions of
the Internet Protocol (IPv4 and IPv6), and tunneling IPv6 packets
over IPv4 routing infrastructure. They allow IPv6 nodes to maintain
complete compatibility with IPv4, which should greatly simplify the
deployment of IPv6, and facilitate transition to IPv6.
- Dual IP layer (also known as Dual Stack): A technique for
providing complete support for both Internet protocols -- IPv4 and
IPv6 -- in hosts and routers.
- Configured tunneling of IPv6 over IPv4: Point-to-point tunnels
made by encapsulating IPv6 packets within IPv4 headers to carry
them over IPv4 routing infrastructures.
- IPv4-compatible IPv6 addresses: An IPv6 address format that
employs embedded IPv4 addresses.
- Automatic tunneling of IPv6 over IPv4: A mechanism for using
IPv4-compatible addresses to automatically tunnel IPv6 packets over
IPv4 networks.
Working Group Summary
There was consensus and no technical objection in the WG for this
document.
Protocol Quality
This document has been reviewed for the IESG by Randy Bush. There is one
or more implementations of each technique in progress.
