;-) Off-list I did suggest `arp -a`. I actually thought that the
broadcast ping would elicit arp responses even if not echo responses,
but on the other hand I don't know what sort of "firewalling" might
interfere with this. I did suggest a port 80 scan with nmap, though,
in case the device in question will response wholeheartedly to that.
I usually prefer the passive approach with arpwatch (cycle the device
and wait for it to announce itself), but I thought ping would be more
accessible.
