I've lost count of the number of times I've needed to do this in IPv4 but been stuck with a single /32. I have also lost count of the number of times I've used a laptop as a router in the days when I had a /28 routed to me. Built in NAT capability for IPv4 that allows a single PPP connection to be shared over wireless seems fairly common these days. We need the equivalent capability in IPv6, just without NAT. _______________________________________________ Ietf@xxxxxxxx https://www1.ietf.org/mailman/listinfo/ietf
