You can also, in most cases, customize your MAC address and change it as per your desires. This means that any computer that can be used to connect to the internet – whether it runs on Windows, a Linux-based OS or Mac OS X – has a MAC address. Unlike many other things, the existence of a MAC address on a computer is not dependent on what Operating System it is running on. The MAC address is an extremely essential part of the networking plane as it is one of the things a network uses to identify devices that are trying to connect to it.Īlso referred to as a Physical Address, a MAC address can also be used to assign static IPS to devices that connect to a network, filter devices using their MAC address to only allow specific devices to connect to a network and to authenticate devices for access through their MAC addresses, among numerous other things. Every device that is designed to be able to (wirelessly or through wires) connect to networks such as internet and WiFi networks – everything from Smartphones to laptops – has a unique MAC address. A MAC (Media Access Control) address is a unique alphanumerical identifier that is assigned to network interfaces so that they can communicate with networks.
