There's probably something to this; since the advent of '95, I've seen
windoze users trying to hit the classful broadcast of the netblock of
their IP address. using /16s across sites makes this sort of stuff
obvious. I've taken to squashing it at PoP-egress, and not trying to
change the customers, as it is undoubtably just some as-shipped default.
