Find MAC Address on Windows 11 PC

A MAC address (Media Access Control address) is a unique identifier assigned to a network interface controller (aka: NIC or network adapter) for use as a network address in communications on the physical network segment. This use is common in most IEEE 802 networking technologies, including Ethernet, Wi-Fi, and Bluetooth.

MAC addresses are primarily assigned by device manufacturers, and are therefore often referred to as the burned-in address (BIA), or as an Ethernet hardware address (EHA), hardware address, or physical address.

MAC addresses are recognizable as six groups of two hexadecimal digits, separated by hyphens, colons, or without a separator.

Knowing the MAC address of a network adapter can help to identify the device or configure networking permissions (ex: MAC filtering) on a router.

This tutorial will show you how to find the MAC address of network adapters (NICs) on your Windows 11 PC.
