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)
I'm sending this via a Lucent card with prefix 0:60:1d. A glance at my ARP table for a wireless-only segment shows 0:4:dd, 0:3:6b, 8:0:20, 0:0:c, 0:c0:b7, 0:d0:b7, 8:0:6a, and more. --Steve Bellovin, http://www.research.att.com/~smb Full text of "Firewalls" book now at http://www.wilyhacker.com
