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. If you want to put a little more effort in, and parse more data out, I recommend using the -online argument to the ip command, which will let you treat every line as a new device: $ ip -o linkġ: lo: mtu 16436 qdisc noqueue \ link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00Ģ: eth0: mtu 1500 qdisc pfifo_fast qlen 1000\ link/ether 00:0c:29:30:21:48 brd ff:ff:ff:ff:ff:ffģ: eth1: mtu 1500 qdisc pfifo_fast qlen 1000\ link/ether 00:0c:29:30:21:52 brd ff:ff:ff:ff:ff:ffĤ: tun0: mtu 1500 qdisc pfifo_fast qlen 100\ link/ĥ: sit0: mtu 1480 qdisc noop \ link/sit 0.0.0.0 brd 0.0.0.The Media Access Control address, also known as the MAC address, is a unique number that comes on every computer. You can trivially get the mac address from this output with awk: $ ip link show eth0 | awk '/ether/ ' I like using /sbin/ip for these kind of tasks, because it is far easier to parse: $ ip link show eth0Ģ: eth0: mtu 1500 qdisc pfifo_fast qlen 1000
