With some network gear (switches and routers), you can limit certain MAC
addresses to certain ports.  For example:
  Socket 1: MAC=00:0C:B0:F3:EE:13 ;Reception PC
  Socket 2: MAC=00:0A:12:4C:2F:22 ;Reception VOIP
  Socket 3: Disabled              ;Lobby spare
  Socket 4: MAC=01:D0:CC:CD:32:01 ;Vending machine
    etc...
This means to hack the network, you need to have the correct MAC address
plugged into the correct wall point, or no data will traverse the wire.
This is one of the systems preferred by fascist network administrators.  Of
course, this can not possibly apply to wireless, as everyone is effectively
on the same "socket".

Cheers,
Tyson.
