Ok bare with me, I'm having an idea that came to me while I was trying to fall asleep.
My router displays the mac addresses for all the computers that it provides DHCP services to. I would like to know how it does that.
Reason: A lot of messageboards I go to are limited to banning people by username and then IP address. Since IP address banning will likely result in someone else getting affected also its a not so nice approach. But if we could ban the MAC address then all would be good (until they got a new card).
This of course requires that each device has a completly unquie mac address which IIRC is the case.
Quick search of this forum and google didn't come up with anything. I'll try again once I wake up.
But if any of you know a way please let me know. Thanks
