Using MAC Address to Uniquely Identify Computers

Marlin099 Re:buy a new network card (561 comments)

Excpet they wouldn't get the MAC address. Since it would go through at least one router, the headers would lose the MAC address. All they would have is the IP address. The router closest to the Cable Modem would be the only one that cares about the MAC addresses of it's subnet. Everyone else works on IP address.
