![]() For instance, the command below disables the eth1 interface: $ ifconfig eth1 down To temporarily change your MAC address, you have to disable the respective interface first. ![]() If you use Ethernet, type the command below to see the adapters’ addresses: $ ifconfig | grep ether Open the terminal and enter the command: $ ifconfig | grep HWaddr Let’s see how your MAC address can be changed without using third-party programs. There are special tools designed to match MAC addresses against geographic coordinates, for instance, the iSniff-GPS script included in Kali. The reason is obvious: if the real MAC address is used, it may be identified during the connection to a network. Pentesters and hackers hide their MAC addresses to prevent the identification of their equipment during the attack. ![]() The MAC address uniquely identifies the device and remains unchanged even after the installation of a new OS as it’s hardcoded in the network interface microchip. 2.4 GHz, 5 GHz, etc.) has a unique MAC address. Routers and switches have unique addresses for every port while in Wi-Fi routers, each wireless interface (e.g. ![]() A device may have several such identifiers for instance, your laptop has a minimum of two: one for the Ethernet controller and another one for the Wi-Fi adapter. Each network interface has (or at least is supposed to have) a unique MAC address.
