WebRTC Leak Test
Run a browser WebRTC check and compare detected candidates with your expected VPN path.
Check whether your browser exposes network information through WebRTC while you're connected to a VPN.
This check is limited. An inconclusive result is not a pass.

How to read the result
Treat this as an observation on this device and this page, not a laboratory certificate. Browser permissions, extensions and reduced user-agent strings can all change what you see.
What Is WebRTC?
WebRTC is a browser technology for real-time communication. Browsers may gather network candidates (ICE/STUN flow) to establish peer connectivity.
What is a WebRTC leak?
A WebRTC privacy concern appears when candidate gathering reveals public network addresses you did not expect during a VPN session.
How this test works
The test asks your browser to gather ICE candidates and compares results against your current observed IP context. Results vary by browser, OS and privacy settings.
Limits
- Results are observations from this device/browser/session, not a complete privacy audit.
- Approximate location and resolver behavior can vary by network path and provider architecture.
- Passwords and checklists stay in this browser.
- A DexterVPN subscription is not required to use these pages.
Privacy statement
These tools are designed to minimize retained data. The IP tool returns only what this site observes for the current request. Browser-based checks run locally where possible. Baseline values for self-tests are saved only in this browser if you choose Save. See the privacy policy.

Frequently asked questions
- Can WebRTC reveal my IP address?
- In some configurations, browser ICE candidate gathering can expose public network addresses. Behavior varies by browser and privacy settings.
- Why can this test be inconclusive?
- Browsers can restrict candidate access or gather limited data. Inconclusive means the test could not determine enough signal in this session.
- Does no public candidate mean complete privacy?
- No. This test checks one exposure path. It does not prove complete anonymity or full VPN security.
