Only true if you're pinging the broadcast address of a network that you
have an interface on, or the system has other knowledge of the netmask/etc.

If you're pinging a remote address, your system (in general) has no way of
knowing if that .0.95 is a broadcast address for a /27, or a normal address
in the middle of a /26 (or one of the other possibilities).

(I've lost the original posting, and can't recall if the OP said if she was
pinging from on-subnet or off-subnet).
