Draft of message to be sent after approval:
From: The IESG <email@example.com> To: IETF-Announce <firstname.lastname@example.org> Cc: RFC Editor <email@example.com>, v6ops mailing list <firstname.lastname@example.org>, v6ops chair <email@example.com> Subject: Protocol Action: 'Deprecating Anycast Prefix for 6to4 Relay Routers' to Best Current Practice (draft-ietf-v6ops-6to4-to-historic-11.txt) The IESG has approved the following document: - 'Deprecating Anycast Prefix for 6to4 Relay Routers' (draft-ietf-v6ops-6to4-to-historic-11.txt) as Best Current Practice This document is the product of the IPv6 Operations Working Group.

Technical Summary Experience with the "Connection of IPv6 Domains via IPv4 Clouds (6to4)" IPv6 transitioning mechanism has shown that the mechanism is unsuitable for widespread deployment and use in the Internet. This document requests that RFC3056 and the companion document "An Anycast Prefix for 6to4 Relay Routers" RFC3068 be moved to historic status. Working Group Summary Discussion in the working group was voluminous and intense. Many additional proposals were considered, such as asking operators to shut down 6to4 service on a stated date via filtering or null routing, not doing so, asking vendors to remove code from products, and so on. This draft represents the intersection of those views - rough consensus in the best possible meaning of the phrase. Document Quality The document was reviewed by numerous people in wide reaches of the community including operators, vendors, and researchers. Personnel Fred Baker is the document shepherd. RFC Editor Note minor tweaks to be processed at editing time. As previously suggested: OLD: This document therefore requests that RFC 3068, "An Anycast Prefix for 6to4 Relay Routers", be made obsolete and moved to historic status. It also obsoletes RFC 6732 "6to4 Provider Managed Tunnels". NEW: This document therefore requests that RFC 3068, "An Anycast Prefix for 6to4 Relay Routers", and RFC 6732, "6to4 Provider Managed Tunnels", be made obsolete and moved to historic status. In response to the IANA review: OLD: Instead, IANA is requested to mark the 188.8.131.52/24 prefix originally defined by [RFC3068] as "Deprecated (6to4 Relay Anycast)", pointing to the present document. NEW: Instead, IANA is requested to mark the 184.108.40.206/24 prefix originally defined by [RFC3068] as "Deprecated (6to4 Relay Anycast)", pointing to the present document. The Boolean values for the address block 220.127.116.11/24 will all be removed.
