The three options are really the same. We already have alternatives to site-local addresses: 6to4 addresses based on PI or RFC1918 IPv4 addresses. We didn't have these alternatives a few years ago. These aren't perfect, which is why we must develop draft-hinden-ipv6-global-local-addr, but they're enough that fec0::/10 seems rather unnecessary in any current IPv6 deployment. They particularly handle the requirements of those organisations that want site-locals because that's what they had with IPv4 and they want the same again.
So I support option A, deprecate site-locals independent of further development of alternatives. We have sufficiently good stopgap solutions. I'm expecting, by the way, that the deprecation will leave fec0::/10 to be treated as global-scope unicast addresses, rather than making fec0::/10 addresses cease to function altogether. -zefram -------------------------------------------------------------------- IETF IPng Working Group Mailing List IPng Home Page: http://playground.sun.com/ipng FTP archive: ftp://playground.sun.com/pub/ipng Direct all administrative requests to [EMAIL PROTECTED] --------------------------------------------------------------------
