An IP address (Internet Protocol address) is a numerical label assigned to each device connected to a computer network that uses the Internet Protocol for communication. An IP address serves two main functions: host or network interface identification and location addressing.
Knowing how to check a computer’s IP address can be useful for various reasons, such as troubleshooting network issues, accessing certain websites or online services, or configuring network settings. There are several methods to check a computer’s IP address, depending on the operating system and network configuration.
To check the IP address on a Windows computer, open the Command Prompt by typing “cmd” into the search bar and pressing Enter. Then, type “ipconfig” and press Enter. Your IP address will be displayed next to “IPv4 Address.”On a Mac, open the System Preferences, then click on “Network.” Select the network connection you are using, and your IP address will be displayed next to “IP Address.”If you are using Linux, open the Terminal by pressing Ctrl+Alt+T. Then, type “ifconfig” and press Enter. Your IP address will be displayed next to “inet addr.”Knowing how to check a computer’s IP address can be a useful skill for troubleshooting network issues and configuring network settings.
