Every device that is part of a computer network has at least one unique hardware ID called a Media Access Control address (MAC address). This MAC address is assigned and attached to the network adapter during the creation process. If your device has more than one network updater or LAN connection such as Ethernet, Wi-Fi, FDDI, Bluetooth or Token Ring, then each LAN connection has a different MAC address.
MAC address is a number or unique identification code to identify each device on a computer network. MAC addresses are composed of 6 2-digit hexadecimal numbers, separated by colons. MAC address is also often referred to as a hardware address or physical address. In identifying a device on the network, the MAC address works in conjunction with the IP address. In the OSI (Open System Interconnection) model, MAC addresses are at layer 2 and IP addresses are at layer 3.
Is this MAC address important enough to know? There is a reason you might need to know the MAC address of a device. When you are setting up your router, you can filter which devices are allowed to connect to the network based on their MAC address. You can find MAC address in Windows 10 very easily. Here’s how:
