Locating your MAC Address

To access Rose-Hulman's network, your network card must be registered with IAIT. If you cannot use the Automatic Registration tool or your device does not have a web browser you must submit your MAC address to IAIT Help Desk.

A MAC Address is a 12 digit combination of numbers and certain letters (A-F). It is split into groups of two letters and each group is separated by spaces, dashes, or colons. An example of this would be 12:34:56:78:9A:BC.
