Just not only. I see the future as IPv4->NAT->limited, IPv6->Native.

How do you (reliably) talk with IPv4-only hosts via the internet when
you're on an (IPv6 natively connected) IPv6-only ethernet?


1st: who says its IPv6 ONLY ethernet? IPv4 can and should stay. Maybe through crappy NAT or proxy. Maybe only to assign DNS ;-)
2nd: IPv6 maps IPv4 addresses into a specific IPv6 prefix. So if you talk purely IPv6, you can address an IPv4 host by using the ::ffff: prefix.
