You can see both the wired ethernet card (enp2s0) and the wireless wlp3s0 card (above). The MAC addresses look like XX:XX:XX:XX:XX:XX, which is 12 digits long and divided into 6 fields of 2 characters each, with the letters being separated by colons “:”. The Media Access Control (MAC) address of the ethernet card is d0:17:c2:12:3c:cd, while that of the wireless network adapter, wlp3s0, is a2:58:a6:6a:29:04.

In my case, d0:17:c2 indicates that my device was made by ASUS, the first manufacturer listed in the first set of numbers and letters. The final 12 digits represent a unique hardware identification number.

While the network card is active, the MAC address cannot be changed. As a result, alter the MAC address before you have to physically remove the network card. Here’s an example of how to do it with the ip command; just swap out “Device” for the name of your network gadget.

A successful MAC address change from the previous display (d0:17:c2:12:3c:cd) to the current display (00:00:00:00:00:01) is shown in the following screenshot.

The problem with the manual method is that it will not stay changed after a reboot.
