What is a MAC Address?

In computer Networking, every computer has a MAC address that uniquely identifies it on a network. A MAC address is also referred to as a hardware address, adapter address, or physical address. MAC addresses are formatted in Hexadecimal digits only (0-9,A-F), and are 48 bits (12 characters) long. They are usually displayed as six groups of two characters and separated by ':' or '-'. Another way is to use four characters separated by periods.

How do I register a MAC Address?

The Stevens Campus relies on 802.1x authentication for student machines. This does not require registering the MAC address. Information on configuring machines to use 802.1x can be found on the 802.1x wiki article. Please read the article on 802.1x and familiarize yourself with how to enter your Stevens account credentials.

Because not all machines are 802.1x capable, students are also allowed the registration of one MAC Address to allow machines to connect to the wired network in their on-campus dorm room. Please refer to the wiki article documentation on Registering a MAC Address for information and instructions.
