Mac Address Help

Some PennNet implementations on campus require users to register their network adapter's MAC address in order to gain access to the network. Additionally, some other services on campus require that a MAC address be registered in order to allow access to a service from a particular host. The information below provides users with guidance on how to locate the MAC addresses of their network-capable devices.

What is a MAC Address?

A Media Access Control address (MAC address) is a unique identifier assigned to most network adapters or network interface cards (NICs) by the manufacturer. It may also be known as an Ethernet Hardware Address (EHA), hardware address, adapter address, or physical address.

A modern computing device is likely to have more than one MAC address as each network interface has its own unique address (wired and wireless). Be sure to choose the MAC address associated with the correct network adapter for the network you wish to connect to.

What does it look like?

When looking for a MAC address, look for a string of 12 characters (0-9, A-F) that looks something like any of the examples below:

  • 0A-B2-3A-24-1D-C2
  • OAB23A241DC2
  • 0A:B2:3A:24:1D:C2
