Changing MAC Address Using macchanger
The macchanger tool is designed to alter the MAC address of a network interface. It provides a straightforward way to change the unique identifier of a device on a network.

Firstly, let’s install macchanger using apt-get if we haven’t already:

Step 1: Find your MAC address and network interface

Type ip link show in terminal

Step 2: Install macchanger

On Arch Linux or Manjaro:

sudo pacman -S macchanger

On Fedora, CentOS, RHEL:

sudo dnf install macchanger

On Debian, Ubuntu, Linux Mint, and Kali Linux:

sudo apt install macchanger

Important! You’ll be asked to specify whether macchanger should be set up to run automatically every time a network device is brought up or down. This gives a new MAC address whenever you attach an Ethernet cable or re-enable WiFi.

I recommend not running it automatically unless you really need to change your MAC address every time. So, choose No (by pressing the tab key) and hit Enter key to continue.

Verify Changes: You can verify that the MAC address has been changed by running:
macchanger -s eth0
ip link show

Reset the MAC address using macchanger:

sudo macchanger -p eno1

Verify Interface Name: mac address name
ip link show
ip link show eno1
