dhcp and foreign ip

[Pol Hallen <deben@fuckaround.org>]

Hi all :-)

An easy environment: 1 server 2 lans:

192.168.1.0 - local lan1
192.168.2.0 - local wlan0

only one dhcp server manages these 2 lans

Sometimes I see inside the arp table (from wlan0) a strange IP like:

10.168.245.246 or similar

what does it mean?
Could be a PC with static IP goes inside my lan (via wireless) or what?

thanks for help!
