What is a MAC address?

A MAC (Media Access Control) address is a unique identifier assigned to every active network device that has a Network Interface Card (NIC). A MAC address is 12 characters long, consisting of digits (0-9) and letters (A-F) and is usually found in a device's settings. All devices that can connect to the internet will have a MAC address; therefore, it is a vital piece of information for troubleshooting network issues.
