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.

General instructions

The MAC address will be listed in the network settings for your device. The instructions will vary for obtaining the wired or wireless MAC device. If it is a university-owned computer, it may be listed on the computer label, listed next to HW Address. You can find your MAC address without having to be connected to the Internet.

If you are successfully connected to the Internet, you can find your public IP Address is by searching What is my IP address in Google Search. Google will then display your public IP address.
