That's nice (as long as your routers ignore the all zeros anycast address), but the question was: how do we write down IPv6 prefixes? Are we ok with simply leaving off the undefined part, or do we insist on proper inclusion of the zeros? If the former, how do we avoid ambiguity for prefixes such as ::ffff/96? -------------------------------------------------------------------- IETF IPv6 working group mailing list [email protected] Administrative Requests: https://www.ietf.org/mailman/listinfo/ipv6 --------------------------------------------------------------------
