Network interfaces use the addresses to communicate with one another. It enables every device to connect to the Internet or a local network to get recognized by its unique 12-character code. MAC or Media Access Control address is an identifier connected to each network interface controller (NIC)- an ethernet or wireless. You need to keep one factor in mind that after changing the address, the new one becomes active, but it is only after rebooting your network card or Windows PC. In this article, we have given you a few ways to cope with the problems and how to change Mac address. But sometimes, a few users may have to spoof the address of their Windows computer to resolve some issues or network restrictions. (Finally, were you to use a Proxy or NAT, then the MAC address would be reset in that way, but this is probably not what you are looking for.Generally, most people don’t spoof MAC address of a network card. The physical port number can be tied to a specific IP address and MAC address requirement.īesides a proper Managed Switch, many Routers, or small computers with multiple ethernet ports have the ability to enforce such restrictions. For example, with a Managed Switch, each PC can be plugged into a separate port. The best thing to do would be to have a middle-man device which controls the traffic. Properly securing a machine when someone has physical access is quite complex and depends on the specific requirements.Īnd besides that, could someone just unplug the network cable and plug it into a a separate device for which they have root access? However, with physical access to the machine, there are many possible ways to bypass the user account controls, and gain administrator access anyway. So, if you do not trust the user, or want to reduce the risk of viruses, you should certainly run a non-administrator account. (There may be network cards which use a fixed MAC address, but I've not yet heard of them.)Īs the comments suggest, an Administrator account in Windows can adjust the MAC address, as well as the IP address.
