VPN Leak Test
One-click check of your VPN: IP, IPv6, WebRTC, timezone and language leaks.
What this test checks
Connect to your VPN, open this page and the test runs automatically. It checks the five most common ways a VPN user is identified:
| Check | What a leak means |
|---|---|
| VPN detection | Your IP belongs to a home provider, so websites see your real connection |
| IPv6 leak | Your IPv4 traffic goes through the VPN but IPv6 does not, exposing your real IPv6 address |
| WebRTC leak | Your browser reveals another public IP through WebRTC. See what is a WebRTC leak |
| Timezone | Your computer's timezone differs from the VPN location, which sites use to detect VPNs |
| Browser language | Your language setting points to another country. Common for travelers, so treated as a weak signal |
The result is a privacy score from 0 to 100 with what to fix. Share it with the Share your privacy score button: the shared card contains only the score and pass/fail results, never your IP address or location.
How to fix common leaks
- No VPN detected: make sure the VPN is connected and not set to bypass your browser (split tunneling).
- IPv6 leak: turn on IPv6 leak protection in the VPN app, or disable IPv6 on your device or router.
- WebRTC leak: enable WebRTC protection in the VPN app or browser extension, or see the steps on the WebRTC leak test page.
- Timezone mismatch: set your computer's timezone to the VPN location, or choose a server in your own timezone.
What this test cannot check
A DNS leak test needs a dedicated DNS server that records which resolver looked up a unique test name. This site does not run one, so DNS leaks are not checked here. Read what is a DNS leak to check your settings, and use your VPN provider's own DNS leak test.
Frequently asked questions
Why is my VPN detected even though it works?
Most VPN servers run in data centers, and their address ranges are known. Detection does not mean your real IP leaked; it means sites can tell you use a VPN.
Does a high score mean I am anonymous?
No. It means your connection hides your IP and location well. Accounts, cookies and browser fingerprinting can still identify you.
Should I run the test without my VPN?
Yes, once, to see what websites see from your real connection. Then connect and compare.
