WebRTC Leak Test

A WebRTC leak can happen when a browser exposes network addresses through WebRTC connection candidates. This matters for VPN users because a different public IP discovered through WebRTC may reveal a real network outside the VPN tunnel.

This free WebRTC leak test checks for public and local IP addresses that your browser may reveal. It compares WebRTC results with your visible public IP address so you can understand whether your VPN, proxy, or privacy setup is working as expected.

Who should use this test?

Use this page if you search for terms like WebRTC leak test, VPN leak test, real IP leak checker, or browser IP leak test. It is especially useful after enabling a VPN, changing browser privacy settings, or switching between Wi‑Fi and mobile data.

For a broader check, compare this result with the main IP location tool and the IP lookup guide.

Safe means the test did not find a different public IP address through WebRTC. Possible Leak means WebRTC found a public IP that is different from the main detected IP. Local IPs means only private addresses were found, which is common on some networks and browsers.

Modern browsers may hide local IP addresses with mDNS. Because of this, a clean result means no leak was detected during this browser-based test; it does not guarantee that every privacy risk is impossible in every environment.
