Check whether your browser is exposing local or reflexive network candidates.
An IP leak test checks whether your browser exposes local network candidates, reflexive public IP data, or other connection hints that weaken proxy privacy. Use it before trusting a VPN or proxy route, because one exposed candidate can invalidate the anonymity story fast.
Detailed signals
More details
A browser leak test can surface host candidates, public reflexive candidates, and the kind of network exposure your session is showing before you trust a route.
Reverse DNS comes from the live reputation checker. WebRTC candidates come from the browser. No pretend DNS-leak score is shown until a real probe exists.
This first pass does not claim full DNS-leak coverage. It gives you the network exposure signals that are actually available in-browser.
