How to find your MAC and IP Addresses

Wired and Wireless MAC addresses each have a unique set of characters.

You must be sure you have selected the Wireless address when registering your computer, or you will have to re-register with the correct MAC address.
Contact the ITS Help Desk at 282-HELP when viewing your computer's information if you are not sure which is the correct MAC address.
