Find your IP or MAC address

A MAC address is a device's wireless or wired (Ethernet) physical address. It is assigned by the manufacturer and will consist of 12 characters, most often displayed with a colon or hyphen separating every two digits (an octet). An example would be 01:a2:b3:c4:d5:e6.

An IP address is a unique identifier for your device, assigned by a network once you connect successfully. It consists of four parts separated by dots. An example would be 141.219.xxx.xxx, with the x's being numbers.
