but the reality is ipv4 works and ipv6 doesn't. and unless the ivory
tower purists get off their doomed thrones, ipv6 will die stillborn. in

there are more ipv4 nats within a 1km radius of here than there are
v6-enabled networks on the planet. and i am at the nexus of ipv6
deployment in the world, networking central in tokyo.

the reality is you have a choice. nat-pt or ipv4 with massive natting
forever. it's not a choice i like, but it's life. get over it.
