What is the WebRTC Leak Test?
WebRTC is the browser technology behind video calls. To connect you directly to other people it can ask your browser for its network addresses — and websites can ask too. If you use a VPN, WebRTC can sometimes reveal your real public IP address even though normal web traffic goes through the VPN. This is called a WebRTC leak.
This test contacts public STUN servers, collects every address your browser exposes, and compares them with the IP address websites normally see. Matching addresses mean no leak; a different public address means a possible leak. Local addresses are shown too, although modern browsers hide them behind random .local names. Results appear in about six seconds and everything is done in your browser.

Questions people ask
What is a WebRTC leak?
WebRTC exposes your public or local IP to websites, even behind a VPN or proxy.
How do I fix it?
Disable WebRTC in your browser or use an extension or VPN that prevents leaks.
Why does it show .local addresses?
Browsers hide your local IP behind random mDNS names for privacy. This is normal and safe.
Does it work without a VPN?
Yes. Without a VPN both addresses match, which shows no additional exposure.
Why are no candidates found?
WebRTC may be disabled, or your network blocks the STUN test server.
