If you are using a Windows computer and you wish to view your MAC address, the procedure is relatively simple. In this example, 00:40:96 is the OUI that identifies this MAC address as belonging to a Cisco Aironet product. The following is an example of a valid MAC address: Tracking Devices – Because every MAC address is globally unique, it is possible for software to track which locations and networks individual computers connect to.After the time limit has been reached, they will sometimes ban a MAC address, but spoofing your address will allow more free access. Identification and Temporal Services – Often coffee shops and airports will only permit a short amount of free Internet (30 minutes to an hour).Authentication Applications – Sometimes ISPs and other network services require a user to sign in or log on with their MAC address.Address Filtering – some network administrators only allow specific devices to connect to a network, and they make filtering decisions based on MAC addresses since they are globally unique.

This is most typically done for servers since it would be a disadvantage if their IP addresses were constantly changing. Static IP’s – If a network administrator didn’t want to use DHCP, they can configure static IP addresses.The following are just a few of uses of MAC addresses: If you want to see who made your network card, simply Google the first six digits of your MAC address. The remaining 6 digits identify a unique network card specific to any given manufacturer. MAC addresses are composed of 12 hexadecimal digits, and the first six identify the network card manufacturer. Also understand that each network card has a globally unique MAC address that is composed of two parts – the OUI (Organizationally Unique Identifier) and a unique ID. As the name implies (Media Access Control), they are used to control and identify different computing systems as they connect to a layer two medium such as a wireless network or a LAN switch. Unlike an IP address (a layer 3 address), MAC addresses operate at layer two of the OSI model. What is a MAC Address, and What Are They Used for? That said, users also need to learn how to spoof their MAC address. In this particular tutorial we will be talking about macchanger but when most people think about spoofing an address, they typically think of masking their IP address with NAT or a VPN tunnel. One fundamental skill that any knowledgeable hacker needs to learn is how to spoof various addresses.
