A new Request for Comments is now available in online RFC libraries. BCP 198 RFC 7608 Title: IPv6 Prefix Length Recommendation for Forwarding Author: M. Boucadair, A. Petrescu, F. Baker Status: Best Current Practice Stream: IETF Date: July 2015 Mailbox: mohamed.boucadair@orange.com, alexandre.petrescu@cea.fr, fred@cisco.com Pages: 6 Characters: 10818 See Also: BCP 198 I-D Tag: draft-ietf-v6ops-cidr-prefix-03.txt URL: https://www.rfc-editor.org/info/rfc7608 DOI: http://dx.doi.org/10.17487/RFC7608 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 implementations of routing and forwarding should therefore impose no rules on prefix length, but implement longest-match-first on prefixes of any valid length.
