This is of great use for accessing BaseStations that are using MAC Address-based authentication. Awesome part is with a wireless sniffer like KisMAC you can also see the MAC addresses of users on that basestation to clone, so you know where to start. And if DHCP is not available... well then shit, it's not like every basestation happens to work on 192.168, or 10.10, and it's not like all of their basestation IP addresses aren't the base-ip of that range (192.168.0.1 / 10.0.0.1) that would be ludicrous, lol. Go wardriving a bit man, you'll see. =) When you come to a odd basestation you can't associate with properly, and it doesn't require a password, 4 times out of 5 it is using MAC authentication.
