A new Request for Comments is now available in online RFC libraries. BCP 196 RFC 7526 Title: Deprecating the Anycast Prefix for 6to4 Relay Routers Author: O. Troan, B. Carpenter, Ed. Status: Best Current Practice Stream: IETF Date: May 2015 Mailbox: ot@cisco.com, brian.e.carpenter@gmail.com Pages: 10 Characters: 20894 Obsoletes: RFC 3068, RFC 6732 See Also: BCP 196 I-D Tag: draft-ietf-v6ops-6to4-to-historic-11.txt URL: https://www.rfc-editor.org/info/rfc7526 DOI: http://dx.doi.org/10.17487/RFC7526 Experience with the 6to4 transition mechanism defined in RFC 3056 ("Connection of IPv6 Domains via IPv4 Clouds") has shown that the mechanism is unsuitable for widespread deployment and use in the Internet when used in its anycast mode. Therefore, this document 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. It recommends that future products should not support 6to4 anycast and that existing deployments should be reviewed. This complements the guidelines in RFC 6343. This document is a product of the IPv6 Operations Working Group of the IETF.
