Native IPv6 behind IPv4-to-IPv4 NAT Customer Premises Equipment (6a44)
Draft of message to be sent after approval:
From: The IESG <firstname.lastname@example.org> To: "Nevil Brownlee" <email@example.com> Cc: The IESG <firstname.lastname@example.org>, <email@example.com>, <firstname.lastname@example.org> Subject: Results of IETF-conflict review for <draft-despres-6a44-02.txt> The IESG has completed a review of <draft-despres-6a44> consistent with RFC5742. This review is applied to all non-IETF streams. The IESG has no problem with the publication of 'Native IPv6 Behind NAT44 CPEs (6a44)' <draft-despres-6a44-02.txt> as an Experimental RFC. The IESG would also like the RFC-Editor to review the comments in the datatracker (http://datatracker.ietf.org/doc/draft-despres-6a44/) related to this document and determine whether or not they merit incorporation into the document. Comments may exist in both the ballot and the history log.

Technical Summary In customer sites having IPv4-only CPEs, Teredo provides a last resort IPv6 connectivity [RFC4380] [RFC5991] [RFC6081]. However, because it is designed to work without involvement of Internet service providers, it has significant limitations (connectivity between IPv6 native addresses and Teredo addresses is uncertain; connectivity between Teredo addresses fails for some combinations of NAT types). 6a44 is a complementary solution that, being base on ISP cooperation, avoids these limitations. 6a44 uses specific prefixes assigned by local ISPs (rather than the anycast address used by Teredo, an evolution similar to that from 6to4 to 6rd). The specification is complete enough for actual deployment, including with independently written codes. Working Group Summary This document is in the Independent Stream, and is under RFC 5742 review by the IESG. Document Quality Ralph Droms reviewed the document according to RFC 5742 and recommends responding that the IESG has no problem with the publication of 'Native IPv6 Behind NAT44 CPEs (6a44)' <draft-despres-6a44-01> as an Experimental RFC. Personnel Ralph Droms is managing the RFC 5742 review of this document. RFC Editor Note The IESG has concluded that this work is related to IETF work done in WGs behave, softwire and sunset4, but this relationship does not prevent publishing.
