That is the Media Access Controller (MAC) address of the Ethernet card. It is “burned/hardwired” into the card itself and is a permanent part of the card. Each and every Ethernet card in the world has a unique MAC address.
Now let me guess… You have a cable MODEM which has married itself to a specific Ethernet card—will only “talk” an Ethernet card with that MAC address? I have found one way so far to work around this mechanism. The SMC Barricade Broadband router (http://www.smc.com/smc/pages_html/homef.html) has the ability to clone a MAC address. That is, it sites between the MODEM and the married Ethernet card and a user can instruct it to clone the Ethernet card’s MAC address. Once cloned that is the MAC address that the Barricade present to the cable MODEM. The MODEM is actually “looking” at the Barricade, but is deceived by the barricade into “thinking” it is looking at its spousal Ethernet card. Larry
