I have a Motorola SB5100 Surfboard cable modem. I need the modem's MAC address, but I've lost the sticker that had the number on it. Isn't there a way that I can ping the modem and get this information?

arp -a displays the arp table from your pc. if youre directly connected to the modem it should be in there. if youre not directly connected (say, going through a wireless router) it may just be easier to connect the modem to the pc for a minute, ping it, then do an "arp -a"

That should give you the internal interface's MAC address, if you need the external you'll probably need to log into the modem's web interface.
