Is Your VPN Really Protecting You?
An online VPN test that shows which address and network websites actually see — a data center or VPN provider, or your own internet provider — and whether anything goes around the tunnel: DNS, WebRTC, IPv6 or split tunneling. It compares what this site, other sites, our own DNS server and your browser report, and sums it up in an anonymity score from 0 to 100.
How to Check if Your VPN is Working
Turn the VPN on and pick any server before running the test.
The tool asks this site and two other services which address they see, looks up a few one-off names only our DNS server answers, collects the addresses WebRTC hands out and reads your device clock.
VPN on, off, or on with a leak — together with the network and location websites see and what each card compared.
Turn on WebRTC protection in the browser or the VPN app, use the VPN’s own DNS, switch IPv6 off or route it through the VPN, and turn split tunneling off for sites that must not see you.

What is checked, and what a leak in each place means
Five checks, and each one looks at a different route out of your machine. A failed check does not mean the VPN is broken — it means one specific path goes around the tunnel.
| Check | What a leak there means |
|---|---|
| WebRTC Leak Test | The browser can hand a website your real address directly, through a STUN request that bypasses the tunnel — even while every page loads through the VPN. |
| DNS Leak Test | Name lookups go to your provider’s server instead of the VPN’s. The traffic itself stays encrypted, but the list of sites you visit is visible to the provider. |
| This Site vs Other Sites | The VPN sends some sites around the tunnel (split tunneling), so those sites — often the ones in your own country — see your real address. |
| IPv6 Leak Test | The VPN tunnels IPv4 only, so IPv6 connections leave directly, carrying your real address. |
| Timezone Check | The address says one country and the browser clock says another. Nothing leaks, but the mismatch itself reveals that a VPN is in use. |
What this check cannot tell you
- Only what is visible from the browser is examined. There is no way from here to confirm that the VPN encrypts your traffic — only to show which routes go around it.
- “No leaks found” means “nothing leaks in these five places”, not “you are anonymous”: the browser fingerprint, cookies and signed-in accounts stay exactly as they were.
- Time zone and fingerprint are not address leaks but tells: they identify you even when the tunnel works perfectly.
