How to find your MAC Address

The following instructions will assist you in finding the MAC address of your network card. The MAC address, sometimes called the physical address, adapter address, or the hardware address, allows us to identify you on the network so that we can assign you a TCP/IP address. It is a twelve-character sequence that usually looks like this:

00-E0-29-44-9b-2b -OR- 00:E0:29:44:9b:2b
