A MAC (Media Access Control) address is a unique ID assigned to every internet-connected machine that allows it to be identified when connected to a specific network.
To find the MAC address on your Windows computer:
- Click on the Start menu in the bottom-left corner of your computer. Select Run or type cmd into the search bar at the bottom of the Start menu to bring up the command prompt.
- Type ipconfig /all (note the space between the g and /).
- The MAC address is listed as series of 12 digits, listed as the Physical Address (00:1A:C2:7B:00:47, for example). Each network adapter (wireless, Ethernet, etc.) has a separate MAC address.
To find the MAC address on your Apple computer:
- Choose System Preferences from the Apple menu.
- Select Network.
- Choose Airport for the wireless adapter MAC and click Advanced (the MAC address is listed as Airport ID).
- Choose Built-in Ethernet and click Advanced and Ethernet (listed as Ethernet ID) for the network cable adapter MAC.
