You can identify a MAC address by its format - a series of 12 hexadecimal digits arranged as “00-00-00-00-00-00-00.” Finding the MAC addresses on a Windows 10 PC If you use virtualization software, there can be even more! Since MAC addresses are tied to network cards and not their PCs, it is quite common to see one PC host multiple MAC addresses. If your PC has both Ethernet and Wi-Fi capabilities, that means that it has two separate adapters - one wired and the other wireless. This entire process is called MAC filtering. Any PC whose MAC address is on a whitelist is allowed access to the network ports, while those on blacklists are denied access or blocked.
If you want to manage access rights to a network, it can be done easily using these MAC addresses.
A Media Access Control (MAC) address is a unique identifier assigned to each network card - and by extension, the PC to which it belongs - in a computer network. All computers use a piece of hardware called a network interface controller (also called a network card) to connect to all networks, local and wide.
