Looks to me like it's not set.  Because there's no active connection,
there's no foreign address.

A socket that's listening won't have a foreign address set, and a socket
that's connected will.

I noticed on Linux, it looks like this:
iago@darkside:~$ netstat -a | grep LISTEN
tcp        0      0 *:8001          *:*                LISTEN
tcp        0      0 *:3306          *:*                LISTEN
tcp        0      0 *:http          *:*                LISTEN
tcp        0      0 *:ssh           *:*                LISTEN
tcp        0      0 *:https         *:*                LISTEN

Probably 0.0.0.0:0 is just Windows's way of saying "not set"?
