VPN Leak Test
Run a fast browser-based VPN leak test for IP exposure, WebRTC leaks, and encrypted DNS reachability. Use it as a practical first-pass privacy check before you trust a VPN session.
How This VPN Leak Test Works
This tool combines the most useful browser-visible privacy signals into one fast check. It looks up your public IP and network organization, tests WebRTC candidate exposure inside the browser, and probes major DNS-over-HTTPS endpoints to see whether encrypted DNS is reachable from your current session. That combination helps you spot the most common VPN failure modes without installing extra software.
What This Test Can and Cannot Prove
This page can quickly tell you whether your browser is exposing extra IP addresses through WebRTC and whether your connection currently looks like a known VPN or datacenter network. It can also confirm whether major encrypted DNS endpoints are reachable. What it cannot do is prove the exact resolver path for every DNS request, because a normal browser page cannot inspect your operating system DNS stack directly.
When to Use It
- Right after connecting to a VPN for sensitive work
- After switching servers or protocols such as WireGuard and OpenVPN
- After browser updates that may reset WebRTC behavior
- Before streaming, remote work, or location-sensitive browsing
What to Do If You See a Leak
Start by fixing the browser layer first. Disable or limit WebRTC if you do not need browser video calling, turn on DNS leak protection inside the VPN app, make sure kill switch is enabled, reconnect to a different server, and rerun the test. Then run a dedicated DNS leak test and speed test to verify both privacy and performance.
