This page connected over unknown. A missing family means it is unavailable on this connection or the family-specific check was blocked.
Browser security check
The result will appear as soon as your browser identifies itself.
Why updates matter: older browsers can miss fixes for malicious-page exploits, browser sandbox escapes and phishing protection.
Version check only: browsers usually expose the major version, not proof of the latest patch.

Under the surface
Detecting…Interpret the result
A browser shares enough information to make websites work. Risk appears when many small signals are combined and stored over time.
It identifies your internet connection and rough area. A VPN can replace the public IP a site sees, but does not make you anonymous by itself.
Screen size, time zone, language and graphics hardware can help distinguish one browser from another—even without cookies.
Your exact GPS location, camera and microphone require browser permission. This diagnostic never requests them.
Quick answers
Your public IPv4 and IPv6 addresses are tested separately at the top of this page. They are the addresses your internet provider or VPN presents to websites; some connections provide only one family.
Your device may be on an IPv6-only or IPv6-preferred connection, with IPv4 translated or shared by the provider. The IPv4-only check can also be blocked by a VPN, firewall, DNS filter or content blocker.
Usually no. IP geolocation commonly identifies a country, region or city and can be wrong. Exact location normally needs explicit device permission or information you provide.
Many providers assign dynamic IPs. Switching networks, reconnecting your router, using mobile data or enabling a VPN can change the address websites see.
No. Private browsing mainly limits history and cookies stored on your device. Websites and your network still see connection information.
Version alone cannot prove a browser is secure. This check compares the major version your browser exposes with current official release data. Open the browser’s own update screen to confirm the latest security patch is installed, then restart the browser to apply it.
No diagnostic history is created. Most values are calculated inside your browser. A server must briefly receive your IP to deliver any web page, including this one.
