Manage MAC Address

A media access control address(MAC address) is a unique identifier assigned to a network interface controller(NIC) for use as a network address in communications within a network segment.

The MAC address does not go further, do not go outside the LAN, do not go outside the first jump from the first router. So as soon as you go through the first router from your PC, your MAC address is no longer being shared.

The first three sets are used to identify the manufacturer of the device, and then the manufacturer assigns another three sets to particular devices as is decided.

What we gonna use to change our mac address is macchanger.

A good way to change MAC address would be a script.

Using crontab on root user.

Adding @reboot macchanger -r eth0 at the bottom. In this way, ur machine's MAC address will change every power on.
