MAC address short form of Media Access Control Address, is a address that uniquely identifies you computer. For every network card on your computer there is a MAC address, which comes built-in. This applies to all types of network cards be it Ethernet or WiFi. Whether you are using a wired connection or wireless one, you do need to transfer data from your computer to some other computer. But how does the other computer find your computer? That is where addresses come in. These addresses are actually hard-coded into the network card. These are given to a network adapter in the manufacturing stage itself. And since these addresses are permanent, they are generally used to prevent devices from accessing a particular network.

A possible MAC address can be 2F-4D-5B-6E-2A-9C. As you can clearly see it is a 12-digit hexadecimal or 48 bits number. The first 6 digits helps to find the manufacturer, while the last six digits find your device. The manufacturers have already got this special number sequence to find themselves as manufactures. Dell has 00-14-22 at the beginning, Cisco has 00-40-96 and so on. These are often referred as OUI or Organizationally Unique Identifier. The last 6 digits or three bytes is the NIC (Network Interface Controller) specifier. A possible question now arises that why would someone like to change their MAC address? It is for so many reasons. If your network limits access to some MAC addresses, then you can change it and have the network access. If a network filters out access based on MAC address, then you can sniff out a legitimate MAC address, change your MAC address and connect. If you want privacy over surfing or any network activity, you could change your MAC address and be untraceable. You can also bypass certain network restriction by spoofing an authorized MAC address.
