When IPv6 offers something end users or ISPs value over IPv4+NAT. Hah, interesting thought! :-) Perhaps we should push for people to use the IPv4+NAT kludge,
A very large number of folks are using IPv4+NAT now, mostly without complaint (or even awareness). I use it myself quite frequently. In a limited (albeit typical) mode of communication, NAT works just fine. IPv6, on the other hand, does NOT work for the vast majority of people on the Internet.
The point was a NAT'ed (masqueraded) network attempting to communicate with another NAT'ed (masqueraded) network. That does NOT work for the vast majority of people on the Internet. And it's a conceptual flaw, rather than a lack of technology penetration (IPv6). -- Christian Kuhtz, Sr. Network Architect Architecture, BellSouth.net <ck@arch.bellsouth.net> -wk, <ck@gnu.org> -hm Atlanta, GA "Speaking for myself only."
