The IESG has received a request from the IPv6 Operations WG (v6ops) to consider the following document: - 'IPv6 Prefix Length Recommendation for Forwarding' <draft-ietf-v6ops-cidr-prefix-01.txt> as Best Current Practice The IESG plans to make a decision in the next few weeks, and solicits final comments on this action. Please send substantive comments to the ietf@ietf.org mailing lists by 2015-04-20. Exceptionally, comments may be sent to iesg@ietf.org instead. In either case, please retain the beginning of the Subject line to allow automated sorting. Abstract IPv6 prefix length, as in IPv4, is a parameter conveyed and used in IPv6 routing and forwarding processes in accordance with the Classless Inter-domain Routing (CIDR) architecture. The length of an IPv6 prefix may be any number from zero to 128, although subnets using stateless address autoconfiguration (SLAAC) for address allocation conventionally use a /64 prefix. Hardware and software algorithms should therefore impose no rules on prefix length, but implement longest-match-first on prefixes of any valid length. The file can be obtained via http://datatracker.ietf.org/doc/draft-ietf-v6ops-cidr-prefix/ IESG discussion can be tracked via http://datatracker.ietf.org/doc/draft-ietf-v6ops-cidr-prefix/ballot/ No IPR declarations have been submitted directly on this I-D.
