WebRTC Candidate Inspection

This local-only check inspects host candidates without contacting a STUN server or other remote service. It cannot confirm whether a public IP address would be exposed in a live WebRTC call.

What is a browser fingerprint?

A browser fingerprint is a combination of details a site can read from a browser, such as language, time zone, screen size, graphics, fonts, and audio rendering. A single value usually does not identify a person, but combinations of signals can make browsers easier to distinguish. This page reports observable signals; it does not claim to measure your uniqueness across all visitors or test DNS leaks, proxy reputation, or IP blacklists.
