How to find the Hardware Address of Your Device

A Hardware Address is a 12-digit number, starting with a 0, and consisting of numbers 0-9 and letters A-F. It is unique (like a serial number) to each network interface. Depending on the device or operating system, it can also be referred to as a MAC address, Physical Address or Ethernet ID.
