It actually doesn't know, it *GUESSES* what IP will be used, and shows 
that one.

It doesn't actually show what IPv4/IPv6 address the TCP connection really 
goes to (I just routed my web server IPv6 address to somewhere that didn't 
work and dumped the traffic, the actual webpage was fetched over IPv4 even 
though ShowIP indicated it was using IPv6).
