actually, it is 127.0.0.0/8

Host 127.0.0.0 seems to be a subnet broadcast address (returned 1 extra pings).
Host localhost (127.0.0.1) appears to be up.
Host 127.0.0.2 appears to be up.
Host 127.0.0.3 appears to be up.
Host 127.0.0.4 appears to be up.
Host 127.0.0.5 appears to be up.
Host 127.0.0.254 appears to be up.
Host 127.0.0.255 appears to be up.

You can try other address too, like 127.254.254.254
It indeed looks like it is all loopback. Result is the same on windows XP.
