A CLEARER VIEW OF YOUR NETWORK

WebRTC leak test

Inspect connection candidates exposed by this browser. The test uses Google STUN after you press Run; it does not request your camera or microphone.

WebRTC exposure

Your next insight starts with a single lookup.

Compare candidates with the expected exit

  1. Record the public exit you expect, using your network configuration and the IP lookup.
  2. Run the WebRTC check. Gathering can take several seconds.
  3. Compare candidate addresses and types with the expected exit. If needed, repeat after one deliberate connection change.

The check gathers candidates from a local peer connection. It does not make an audio/video call or connect two remote users.

Read host, srflx and relay candidates

A host candidate describes a local interface; browser privacy controls may substitute an mDNS hostname. A server-reflexive (srflx) candidate describes an address observed via STUN. A relay candidate describes a TURN relay.

This implementation configures Google STUN and no TURN service, so a missing relay candidate is expected and is not a failure. A private address alone is not evidence that your public IP has escaped a VPN.

An empty result is not a safety certificate

No candidates can reflect browser restrictions, blocked STUN traffic or unavailable networking features. It does not prove the absence of leaks. Conversely, an exposed public candidate needs comparison with your expected route before it can be described as an unexpected exit.

This test does not inspect your system DNS resolver, VPN configuration or every browser application.

Use a reproducible comparison

Read what empty WebRTC results mean, the VPN exit comparison checklist, and the browser privacy guide. The IPv6 test can reveal a separate address-family path.

A little more visibility. A lot more confidence.

Transparent sources, useful diagnostics, and reports you can take with you.
