What we have today is an utter mess. Why else do we have URLs like
http://ipv6.google.com/ or http://www.v6.facebook.com/ ?
Any communication between the V4 and V6 worlds is via application-layer
gateways, such as dual-homed MTAs, just like in the IP/X25 days. It's true
that unlike X25, we also have the option of doing some layer 4
cross-connection using things like SOCKS or NAT64.
