I think there are switches with some intelligence: if the MAC changes on one of the ports, it is blocked. Something of the sort, I don't have the details.
nearly any wireless router do so (or can do)
however be warned than fake Mac (HW) adress are easy: even virtualbox can setup any HW adress you want, and any wireless device begin by advertising the world with it Mac's, so stoling a Mac adress is extremely easy.
Yes, but: - If the PC has the proper MAC, the dhcp gives the correct IP. - If the user sets another MAC, the switch denies entry. There remains the case that the user tries to force the wrong IP. I have heard of (windows) programs that scan the network with a list of IPs and corresponding MACs, reporting to the network manager if a discrepancy is found. It could be used to block that IP in the router. I think it could be done via arp and rarp and some scripting in cron. - -- Cheers, Carlos E.
