> Changing the message from "you don't need NAT anywhere" to "sure, you > can use RFC 4193 ULAs, just don't let us see them on the Internet" > would be a big help. in ipv4, rfc1918 space was needed because of address scarcity. in ipv6, you could use global space inside a nat, if you need a nat. we do not need to perpetuate the 1918 mess. randy
