The easiest way to find your MAC address on Linux is to execute the “ifconfig” command with the “-a” option for “all”. The MAC address is available.

In this article, I will take you through different ways to List/Get/Display/Find MAC Address in Linux. You might be aware of Ethernet Card/Network Card/NIC Controller which works at Network level and is responsible for communicating with other network devices in a Network Topology. It is used in Layer-2 Communication. You can find the usage of MAC address in wide range of Network Devices currently in use. This is typically in-line with IEEE 802 Network technologies.

  1. Aug 18, 2016 Find MAC address in Linux. First, let us find out the MAC address or Hardware address of a Network interface card in Linux. $ ifconfig grep HWaddr. Sample output: enp0s3 Link encap:Ethernet HWaddr 08:xx:xx:xx:xx:x1. Or, $ ip link show.
  2. The second line will always indicate the type of link layer in use on the device, and link layer specific information. For Ethernet, the common case, the current hardware address (MAC Address) and Ethernet broadcast address will be displayed. Second task: change the MAC address of your network devices. Ip link set dev eth0 address 00:80:c8:f8:be:ef.

What is MAC Address

MAC is abbreviated as Media Access Control. It is a unique 48 bit(6-byte) address assigned to a Network Interface. It is almost used in all the Network Devices which has network controller in it. It will always show in this form 00:07:Y7:1C:6L:03.
