RFC status does not have direct connection with "being implemented" or "being deployed" (see all the W3C standards which did not originate in IETF). at N+I tokyo we have been using RFC2766/3142 for IPv6-only net cafe since around year 2000 or something. in June 2007 N+I network team used Windows Vista official releases as the clients. >> their scalability is no worse than IPv4-to-IPv4 NAT. > >That may be true, but it is also irrelevant, given that the current >production network doesn't use IPv4 NAT at all. you are in ARIN region so you are enjoying vast amount of IPv4 address space... come to APNIC region or LACNIC region to experience the pain. i pay $300/mo for PA /29, and it is a real bargain. itojun _______________________________________________ Ietf@xxxxxxxx https://www1.ietf.org/mailman/listinfo/ietf
