The first six digits (three bytes) of a MAC (Media Access Control) address
identify the manufacturer of a network interface card. The last six digits
(three bytes) are the serial number of that particular card.
As Alex said, the MAC address serves only as a unique identifier. The most
useful information that you can get out of the MAC address is from the first
six numbers. You can use them to look up the manufacturer of the card, if
for some reason you are unable to determine their name any other way. Here
is a site where you can look up the name of the card manufacturer:
