About ping123

ping123 shows you what your network looks like to everyone else: where your IP comes from, whether it looks like a real person, and whether anything leaks.

Data sources

How it runs

The site runs on Cloudflare Workers with no servers or databases of its own. Browser-side checks (time zone, WebRTC, fingerprint) are computed on your device.

Languages

ping123 is available in Simplified Chinese, Traditional Chinese, English, Japanese, Korean, Russian and Spanish. Your first visit opens the version matching your browser's language, and you can switch at any time from the top-right corner.

Command line

curl ping123.app returns your IP; curl ping123.app/json returns full details with server-side risk checks.
