How To Find Your Device MAC Address

What is a MAC Address?

MAC Address or media access control address is a unique ID assigned to network interface cards (NICs). It is also known as a physical or hardware address. It identifies the hardware manufacturer and is used for network communication between devices in a network segment. MAC Address usually consists of six groups of two hexadecimal digits.

The network adapters or network interface cards always come with a MAC address which is fed into hardware, usually in read-only memory (ROM), or BIOS system. The physical address is stored into the NIC by its manufacturer, that is why this address is also called a burned-in address (BIA) or ethernet hardware address.

There are several NIC manufacturers; some well-known of them are Dell, Cisco, Belkin. The first three sets of two hexadecimal numbers in a MAC Address identifies the card manufacturer, and this number is called OUI (organizationally unique identifier). OUI is always the same for NICs manufactured by the same company. For example, let's say a network card manufactured by dell has a physical address: 00-14-22-04-25-37, in this address, 00-14-22 is the OUI of Dell which identifies that the device is by Dell. It may be interesting for you to know that all the OUIs are registered and assigned to the manufacturers by IEEE.
