When you are learning networking or troubleshooting it, you would need to know the MAC address.
A computer can have more than one MAC address. It is because the MAC address is a core part of networking, and each networking peripheral device has its own MAC address.
So, your WiFi card has a MAC address, and so does the Ethernet (LAN) port. Even the Bluetooth has one.
The MAC address, also known as the physical address, is a 12-digit hexadecimal code (48-bits) and is represented as MM:MM:MM:SS:SS:SS
In this tutorial, I’ll share the steps for finding the MAC address of your desired networking interface in Linux. I’ll show both command line and GUI methods.
Method 1: Find MAC address using command line
There are serveral Linux networking commands that can be used to get the MAC address of the WiFi or LAN cards.
Basically, use the same command that you use for checking the IP address.
Open up your terminal and use the following command, and it will bring the address of the present network cards in your system:
ip link
And you’ll be met with the following output:
