The IESG has approved the following document: - '464XLAT: Combination of Stateful and Stateless Translation' (draft-ietf-v6ops-464xlat-09.txt) as Best Current Practice This document is the product of the IPv6 Operations Working Group. The IESG contact persons are Ronald Bonica and Benoit Claise. A URL of this Internet Draft is: http://datatracker.ietf.org/doc/draft-ietf-v6ops-464xlat/ Technical Summary: This document describes an architecture (464XLAT) for providing limited IPv4 connectivity across an IPv6-only network by combining existing and well-known stateful protocol translation RFC 6146 in the core and stateless protocol translation RFC 6145 at the edge. 464XLAT is a simple and scalable technique to quickly deploy limited IPv4 access service to IPv6-only edge networks without encapsulation. Working Group Summary: The working group, for the most part, the working group found this uncontroversial; it is a way to deploy an IPv6-only core in a mobile network and use translation to provide access to IPv4 content. The folks working on the software "MAP" technology objected to it as it is a deployment technology simpler than MAP and takes shortcuts that may hobble such deployments in the long term. Remi Despres made suggestions on the list and had some support. However, the suggested approaches were more "different" than "better", and neither built consensus nor demonstrated issues requiring changes to the document. Document Quality: The document is a description of how to build a certain service offering. There are ways to build other service offerings, and they may or may not be better. However, the service offering described has been implemented and in fact works. Personnel: The document shepherd is Fred Baker. The area director is Ron Bonica.
