Your public IP address, where the internet places you, and what your browser tells every site you visit. Plus a WebRTC leak test to check your VPN and an analyzer that classifies any IPv4 or IPv6 address.
Your public IP address, where the internet thinks you are, and what your browser gives away, plus a WebRTC leak test for VPN users and an analyzer for any IPv4 or IPv6 address. The lookup uses this site's own server; nothing is logged or stored, and no third-party IP service is called.
Location comes from Vercel's edge network, which maps IP ranges to places; it can be off by a city or more. Related: Subnet Calculator, Password Generator.

Share on XShare on LinkedInEvery site you connect to sees your public IP address. It's assigned by your ISP (or your VPN), and it's what geolocation databases use to guess your city, which is why the location is approximate and often shows your ISP's hub rather than your street. If you're behind carrier-grade NAT, many customers share one public address and the analyzer will say so.
The WebRTC test matters for VPN users. Video-call technology in browsers can discover your network addresses, and a misconfigured VPN can let your real IP slip out that way. The test asks a public STUN server what address it sees and compares it to the IP above. The IP lookup itself runs on this site's own server using headers its hosting provider already attaches; nothing is logged, stored, or sent to a third-party IP service.
