Finding my MAC address

The MAC (Media Access Control) address is a unique identifier assigned to network interfaces. It's basically the physical address of your network connection.

This means if you have both a wired and wireless connection on your computer, that you have two MAC addresses: one for the wireless adapter and one for the wired.

Here's how to find your MAC address on your computer.
