To find out the Mac address, you will have to use the IP command. To get MAC address Linux computers have, you need to put quite a lot of effort.Īs a Linux user, you should already be aware of commands used to carry out various tasks. For instance, on Mac OS Terminal or the Control Panel on MS Windows as those seem like the obvious methods, right? Well, not necessarily.Īnd in the case of Linux, the process is a bit tricky. This is where the MAC address comes in, letting the device (computer) identify itself to a packet.Īs a computer owner, you might be tempted to tinker with the system settings to modify the gimmick or find out the MAC address. The system would become a bit of a mess, and the packet would get lost. If the packet comes more than once, imagine what would happen if the original computer went offline and another device took the IP address. Say that there is a packet targeting a particular computer connected to a network with dynamic IPs. There is some truth in that statement, but redundancy disappears when we are talking about local area networks, particularly those that have dynamic IPs.Ĭomputers need to have a MAC address to avoid potential problems. Since computers already have multiple unique identification methods, it might seem like the MAC address is redundant. A similar thing applies to Ethernet and Ethernet LAN - addresses are identical. The number is inseparable from an internet connection.įor example, if your computer is connected to Wi-Fi or is part of a local area network, the IP address becomes linked to the Media Access Control address. Now, if you are wondering what the purpose of a MAC address is, the answer is a bit tricky. One can also think about it as a hardware number. The Media Access Control address, also known as the MAC address, is a unique number that comes on every computer.
