One of the "advantages" of MAC addresses is that they are associated, exactly, with each interface and not with the computer in question. The MAC address format looks like the following in hexadecimal: 1A-B2-C3-D5-7F-AA Now, how can I determine the MAC address of my computer's network interface? You just need to enter the command line (cmd) and type the command " ipconfig /all ". Unlike the traditional " ipconfig " command, it displays much more detailed information about each of the network interfaces available on our computer.
Here is an example: The command displays all information related to each interface. An interesting point to consider is that if for some reason you don't have some kind Buy Email Database of interface like bluetooth, wi-fi or whatever, you won't be able to see the information. The Physical address field corresponds to the MAC address. To account for this, other information you can get at a glance is whether the interface has DHCP enabled, connection status, general IP data, and more.
What is the MAC filtering process? In MAC filtering, we mainly have two policies, that of accepting only "white" listed MAC addresses and denying all others, or blocking all "black" listed MAC addresses and allowing everything else. This way, any MAC addresses that are blacklisted or not whitelisted (depending on the policy you followed), will not be able to access the network. However, MAC addresses, although a physical identifier for the network card, can be changed in the operating system.
