Technical Summary

   This document is a product of the 2008-2010 effort to define a
   replacement for NAT-PT [RFC2766].  It is directly derivative from
   Erik Nordmark's "Stateless IP/ICMP Translation Algorithm (SIIT)"
   [RFC2765], which provides stateless translation between IPv4
   [RFC0791] and IPv6 [RFC2460], and between ICMPv4 [RFC0792] and ICMPv6
   [RFC4443].

Working Group Summary

This document represents WG consensus.
The primary issues raised dealt with fragment handling.
An investigation was done to determine how much of a problem not
getting ICMPv6 "packet too big" messages is on the public Internet,
and it was found to be a bigger problem than originally anticipated.
As such, this changed the WG opinion from rough consensus on
one approach to a strong consensus on a different appoach on
the final document.

Document Quality

several vendors are actively implementing the specification.
