Question

How do I find the wireless IP address and/or MAC address on your Mac/Apple computer?

Overview

The Media Access Control (MAC) address is a unique 12-character identifier (e.g. 00:00:00:00:00:0X) for a specific piece of hardware, such as the network adapter located in WiFi devices. It is unique to your device.

The IP address is your unique network identifier when you’re accessing the Internet here at UC Davis. Unlike the MAC address, which will never change on your device, you might receive a different IP address each time you connect to the network. For each device, that number is unique. (e.g. 192.168.12.137)
