How to Find Your MAC Address in Windows 11

Identifying devices on a network can be difficult. Most systems allow their owners to name them, which is why you’ll often find “John Doe’s PC” or “Jane Doe’s iPhone” on a given Wi-Fi network, but those names can’t be trusted because they’re easy to modify. A better way to make sure you’ve correctly identified a given device is to check its media access control (MAC) address. You may need this information for several reasons, including creating a whitelist of devices that are allowed access.

Manufacturers assign MAC addresses to different network adapters such as Wi-Fi radios and Ethernet controllers while they’re being made so any device with connectivity has at least one.
