How to Find Your MAC address in Ubuntu and Other Linux Distros

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:

You can see it beside the BD Address field.

[email protected]:~$ hciconfig 
hci0:	Type: Primary  Bus: USB
	BD Address: DC:41:A9:FB:7A:C4  ACL MTU: 1021:4  SCO MTU: 96:6
	UP RUNNING 
	RX bytes:17895787 acl:275 sco:250783 events:298882 errors:0
	TX bytes:303664302 acl:295384 sco:249895 commands:3380 errors:0

You can also use the bluetoothctl command here.

Method 2: Get MAC address using GUI

If you’re afraid of using the terminal you can use the network settings to get the MAC address details.

I am using Ubuntu with the GNOME desktop environment. If you use some other desktop environments, the screenshots may not look the same.

First, search for settings in the system menu and open the first result.
