Macchanger is simple utility to view, modify, and manipulate MAC addresses for your Network interface cards. Method 1: Change MAC address using Macchanger So either try this method on an additional card or be prepared to restart your network. If you do this on a network interface which is currently in use, probably your network connection will be terminated. Now you may proceed to changing the MAC address. You may want to note it down on a secure place to revert to this original MAC address later on. Link/ether 42:02:07:8f:a7:38 brd ff:ff:ff:ff:ff:ffĪs you can see, in this case, my network interface is called enp0s31f6 and its MAC address is 38:42:f8:8b:a7:68.

Let’s go through each step: Step 1: Find your MAC address and network interface I am going to show the steps for changing MAC address (also called spoofing/faking MAC address). If you want to use the internet beyond that, spoofing your Mac address may trick the network in believing that it’s a new device. One practical ‘benefit’ is that some public network (like Airport WiFi) allows free internet for a limited time. Maybe you don’t want your actual MAC address (also called physical address) to be exposed on a public network? Other case can be that the network administrator might have blocked a particular MAC address in the router or firewall.

Before I show you how to change Mac address in Linux, let’s first discuss why would you change it in the first place.
