What is a MAC Address?

A MAC (Media Access Control) address is a permanent and unique identifier assigned and hard-coded into a Network Interface Card (NIC) or a network adapter. Every network-capable device has a MAC address, whose purpose is to identify devices in a network such as smartphones, computers, WiFi cameras, routers, and more in a LAN (Local Area Network) environment.

A MAC address is a 48-bit address and has a 12-digit format, grouped in twos and separated by the colon (:) or a hyphen (-). The hexadecimal number contains numbers from 0 through 9 and letters A through F. A MAC address is not case-sensitive; therefore the MAC address c7:a2:9d:19:3f:09 is the same as C7:A2:9D:19:3f:09.

As stated above, MAC addresses are used for communication within a LAN setting and are specific to that LAN. On public networks (WAN and MAN) IP Addresses are used for devices' communication purposes.

Spoofing a MAC Address

MAC addresses are hardcoded into devices' Network Interface Cards (NIC) and, therefore, cannot be programmatically changed. However, you can spoof your device’s MAC Address in common Operating Systems such as Windows, MacOS, and Linux.

There are several reasons why one might need to spoof a MAC address. One of the common reasons is to bypass certain network restrictions. Network devices such as routers and switches have a network filter feature (known as MAC Filtering) where a network admin can restrict certain devices from accessing some or all of a network’s resources. If your device has been blocked, you can spoof a different MAC address and bypass the restriction.

If in an organizational network, ensure you have the authority to spoof your MAC address. Some organizations can consider MAC address spoofing as cybercrime, which can attract a penalty.
