I am unaware of any troubleshooting value.  After all, should you want
to scan for hosts, use SNMP.  Or increment your ping address.

Actually, HP Open View uses broadcast pings to discover hosts, and
non-broadcast pings to check whether they are up or down.  Actions can be
taken to monitor even non-snmp supporting hosts this way.

Lots of
simple harmless ways to do the same thing.  Especially since you need to
know the (now variable) local mask to effectively use a directed
broadcast anyway.

True, of course, on your own nets, you know what the masks are, and tell
HPOV about these.

Directed broadcast would be harmless as well if it weren't done to others,
or if they were immune ;-)
