MAC address is a unique identifier of a network card, which is used to identify a device in a local network. It consists of 6 two-character groups, which are separated by colons. Why do you need it? MAC address allows you to manage network traffic, control access to the network and determine the affiliation of a device to a specific network. If you want to know the MAC address of your network card, you need to perform a few simple steps. First, open the command line (in Windows, you can do this by pressing Win + R and entering the cmd command), then enter the ipconfig /all command. In response, you will receive detailed information about the network card settings, including the MAC address. If you are using Mac OS, then in order to find out the MAC address of the network card, you need to open the terminal and enter the ifconfig |grep ether command. In response, you will receive the MAC address of your network card. We hope that this guide will help you quickly and easily find out the MAC address of your network card.
