But the advent of subnetting certainly makes things confusing...  If you
are splitting up net 10 into /24s, ideally you should be able to have
a net 10.255.255.0/24, even though you have no way of knowing whether
10.255.255.255 is your local broadcast or a net-10 directed broadcast.

But yeah...   If you're binding to *.*, then you should get all
broadcasts... including 10.255.255.255, not just the local subnet ones.
