What is a MAC address and how to find it on your PC or Mac

Any device that connects to a WiFi network must be identified on the network by a unique network address. This unique identifier, known as a Media Access Control (MAC) address, helps network administrators or observers track or profile the network activity of all users and location over time.

While you may not have to worry about the MAC address of your device most of the time, there are times when you need to know the MAC address of your network adapter. This way, you can identify the device or configure network permissions on your router.

Whatever the reasons you need your MAC address, we’ll show you several ways to do it on both Mac and PC.

The device manufacturer assigns it the unique identifier and permanently links it. This allows communication between devices on a local network to initiate a connection.

There are two main types of MAC addresses: Universally Managed Address (UAA) and Locally Managed Address (LAA).

The UAA is the most popular type, assigned by the device manufacturer, while the LAA changes the MAC address of your adapter. You can assign the LAA to your network device and it will replace the address assigned by the manufacturer.

The MAC address of the device is sometimes confused for the IP address although both are used to identify your device on the internet, but there are some important differences.

MAC addresses are permanently assigned by the device manufacturer to identify your machine to others, and are designed not to be modified. IP addresses manage the logical routing connection from your devices and networks, and they can change by location.
