Finding a MAC Address A MAC address is a unique number assigned to a Network Interface Card by the manufacturer, not by Cedarville University.
All manufacturers cooperate to ensure that each address is unique.
At times, MAC addresses are separated by colons or dashes. An IP address is a number assigned to some computers by Cedarville University. Check the box it came in for a label. Other times, the actual NIC itself may have a sticker label somewhere on it with the MAC address. Click the down arrow beside the top line and choose the description of your network card.
