What is a MAC address?
A Media Access Control (MAC) address is a 48-bit identifi er associated with the hardware of network equipment. T he
MAC address may also be called the physical address because it is co nnected to the hardware of a device instead of its
software. The MAC address is displayed as a hexadecimal number in th is format: 01-23-45-67-89-AB.
Every device capable of communicating on a network has a MAC addre ss. Network printers, computers, and routers,
whether Ethernet or wireless, all have MAC addresses.
While it is possible to change the MAC address of a network device, it is not common practice to do so. For this reason,
MAC addresses are considered permanent. IP addresses are easily changed, so MAC addresses are a more reliable
method of identifying a specific device on a network.
