About CheckPublicIP.com

A fast, no-nonsense tool for checking your public IP address.

CheckPublicIP.com does one thing well: it shows you your public IP address the moment the page loads, along with your internet provider, approximate location, and connection details. No sign-ups, no downloads, no waiting.

How it works

The site runs on Cloudflare's global edge network, which means your request is answered by a server close to you — usually in a few milliseconds. Your IP address and connection details are read directly from the request itself; we don't send your data to third-party services to display it.

What we offer

• Instant IP check — your public IPv4 and IPv6 address with location and ISP
• IP lookup — details for any public IP address
• Guides — plain-English articles about IP addresses, privacy, and networking
• A developer-friendly API: curl checkpublicip.com returns your plain IP, and /api/json returns full details as JSON
