WebRTC Leak Test
Check whether WebRTC ICE candidates expose local or public IP addresses beyond your VPN or proxy.
Acerca de esta herramienta
VPNs and proxies mask HTTP traffic, but WebRTC can still reveal local network addresses or a different public IP through STUN ICE candidates. This test runs entirely in your browser — nothing is uploaded.
Qué obtienes
- Pass/fail verdict comparing ICE addresses to your connection IP
- List of public and private/local ICE candidates
- Candidate types observed (host, srflx, relay)
- Plain-language explanation when a leak is possible
Cómo usar
Click Run test and wait a few seconds while ICE candidates are collected. Compare the verdict with your VPN or proxy enabled and disabled. Browser extensions that block WebRTC may show no candidates.
FAQ
What is a WebRTC leak?
WebRTC can expose local or public IP addresses through ICE candidates even when VPN or proxy software masks normal browser traffic.
How does this WebRTC leak test work?
Your browser collects ICE candidates via STUN—entirely client-side. The tool compares them to your connection IP and flags unexpected public or local addresses.
Can a VPN prevent WebRTC leaks?
Many VPN apps block or route WebRTC. If candidates still show your real ISP IP or LAN addresses, adjust VPN settings or use a browser extension that disables WebRTC.
Is any data sent to the server during the test?
No—the ICE scan runs locally. Only your already-visible connection IP from the page header is used for comparison.
