I while ago I put this one forward, which is an alternative to Fernando's suggestion that you have to set the whole address: http://tools.ietf.org/html/draft-chown-6man-tokenised-ipv6-identifiers-00 This was based on existing implementations, in Solaris and Linux (as a demonstrator), with the potential for simpler renumbering in mind. It's probably the complete antithesis of what Fernando is trying to achieve, but is aimed at the type of (server) systems that would probably be DNS-advertised anyway.
