Does anybody know where I can locate a list of MAC address prefixes that belong specifically to wireless NIC cards? I am looking for a method of discovering what devices on my network are wireless devices.
Power down the wireless hub and see who calls? ;)
Seriously though - your wireless hub/transmitter may have a queryable arp table that will tell you what's not using the wire....
i've used/seen cards with these prefixes: 00:e0:29 - smc 00:02:2d - orinoco/wavelan cards (lucent/agere) however, there's nothing to stop the vendor from using a given prefix for wired cards as well. more to the point, it's relatively trivial to change the hardware address of the card, so all bets are off (read as: mac address filtering is useless). -- |-----< "CODE WARRIOR" >-----| codewarrior@daemon.org * "ah! i see you have the internet twofsonet@graffiti.com (Andrew Brown) that goes *ping*!" andrew@crossbar.com * "information is power -- share the wealth."
