An IP address (Internet Protocol address) is a unique identifier for a device on the network. Knowing how to find your IP address is important in troubleshooting network problems, setting up network devices, and maintaining network security. This article will detail how to check your IP address on different devices, including Windows computers, Mac computers, smartphones (Android and iOS), and routers.

You can also use online tools to find your public IP address. Visit a website such as "whatismyip.com" or "ipinfo.io" which will automatically display your current public IP address.
