Find a Computer's Hardware Address

Equipment that can connect to any network, including the Internet, use a piece of hardware called a Network Interface Card (NIC). Every NIC manufactured has a unique set of characters referred to as its Hardware, Physical, or MAC (Media Access Control) Address. The address is typically used to recognize the system on the network and give it a logical network ("IP") address, allowing it to connect. It is formatted as a 12-character, hexadecimal (0-9, A-F) number, and is assigned by the network card's manufacturer.

Instructions on this page will help you look up a computer's Hardware Address, which is required to register for the CUMC Wired Network. Only staff in a Certified IT Group will be able to submit the registration form, however you can use these instructions to help gather the information needed. The Hardware Address can also help if you are experiencing connectivity problems on the computer or device.

IMPORTANT: Be very careful to record and enter the address correctly. Every Hardware Address is unique world-wide. A device that uses both Ethernet (wired) and wireless connections will have a different Hardware Address for each connection. If the wrong address is submitted for registration it will not be able to connect, and registration must be re-submitted with the correct address.
