The current reservation is for the ::/8, which contains both :: and ::ffff/96, so does it actually matter? Incidentally, there are situations in which :: can appear validly on the wire (but only as a source address) - with MLD for example, and that's contained within the /96 that you're talking about. -- Colm MacCárthaigh Public Key: [EMAIL PROTECTED] -------------------------------------------------------------------- IETF IPv6 working group mailing list ipv6@ietf.org Administrative Requests: https://www1.ietf.org/mailman/listinfo/ipv6 --------------------------------------------------------------------
