What Is an IP Address? IP Lookup API Docs

WhatIP helps you check your public IP address and current country instantly. You can also continue with the IP lookup tool or the free API docs.

WhatIP shows the public IP visible on the internet. It can be different from the private IP shown inside your router or local network.
