MAC Address Changer

Overview

MAC Address Changer is a Python command-line utility that automates viewing and updating the MAC address of a network interface on Linux systems.

The project demonstrates Python scripting, command-line argument parsing, and interaction with Linux networking tools. It is intended for educational purposes, system administration, and authorized testing in laboratory environments.
