Deprecating the Anycast Prefix for 6to4 Relay Routers
RFC 7526, “Deprecating the Anycast Prefix for 6to4 Relay Routers”, is a Best Current Practice document published in May 2015 by O. Troan, B. Carpenter. It obsoletes RFC 3068, RFC 6732. The canonical text is published by the RFC Editor.
Abstract
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.
What “Best Current Practice” means
Documents the IETF community's recommended operational or procedural practice rather than a protocol specification.
