v6 is completely upward compatible with v4. Watch this:

marajade-[~] mcr 10001 %telnet -6 ::ffff:209.87.252.178
Trying ::ffff:209.87.252.178...
Connected to ::ffff:209.87.252.178.
Escape character is '^]'.

tcp6       0      0 209.87.252.196:43185    209.87.252.178:23       ESTABLISHED

It works fine.  
It uses v4 at the network layer, but the application thinks it has v6.

What we did not do was make IPv4 compatible with v6, or any other new
protocol.  No v7, or any other thing would have accomplished that.
