VPN Check
A VPN should hide your IP, encrypt your traffic and keep your DNS inside the tunnel. This one-click check runs every leak test we have โ public IP, WebRTC, DNS and IPv6, plus VPN / Proxy / TOR detection โ and tells you in plain English whether your VPN is actually working.
Is My VPN Working?
Click Run VPN Check with your VPN connected. The tool pulls together five signals: the public IP your provider sees, the VPN / Proxy / TOR flag from IP intelligence, whether WebRTC exposes a local address, whether an IPv6 address bypasses the tunnel, and whether DNS answers look consistent. It then gives one combined verdict so you do not have to interpret raw data.
A VPN that is active and leak-free protects your real location, IP and browsing history. A VPN with a WebRTC or IPv6 leak still hides part of your traffic while quietly exposing the rest โ which is worse than not using one, because you think you are anonymous. That is why a combined check beats any single test.
Connect your VPN, then click test for a combined verdict.
What the Five Checks Tell You
- Public IP + VPN flag โ if your public address is flagged as a VPN / datacenter / hosting address, the VPN is on. If it looks like a residential ISP, the VPN may be off or misconfigured.
- WebRTC leak โ reveals whether your real local network address is exposed through browser peer-to-peer connections.
- IPv6 leak โ if IPv6 is visible on top of an IPv4 VPN, your IPv6 traffic and DNS may bypass the tunnel.
- DNS consistency โ a stable, consistent DNS resolution suggests your queries ride inside the tunnel rather than bouncing to different resolvers.
The verdict combines these into one of three results: VPN active, no leak ยท VPN active, but something leaks ยท VPN not detected.
VPN Check โ Frequently Asked Questions
The test says my VPN is not detected. Am I unprotected?
Not necessarily. Some VPNs exit through addresses that are not yet flagged as VPN or datacenter by the IP database we use, especially newer or residential-exit providers. The result simply means our detection could not confirm a VPN is active โ combined with the other checks it is still a useful baseline. If you want certainty, try the DNS leak test and WebRTC leak test too.
What does "VPN active but something leaks" mean?
It means your IP looks like a VPN address but at least one check did not fully pass โ for example WebRTC exposed a local IP, or an IPv6 address is visible. The detail line under the verdict names exactly which item is leaking so you know what to fix (disable WebRTC, enable a kill switch, or turn off IPv6 for the VPN).
Why run all five checks instead of just one?
A VPN that only hides your public IP is still leaking if WebRTC, IPv6 or DNS expose the rest of your identity. Each check covers a different failure mode, so only together do they give a trustworthy "is my VPN really working" answer. This page bundles them for convenience โ each check is also available as a standalone tool (see Related Tools).
Is this a leak test for any particular VPN provider?
No. This is a neutral, provider-agnostic check that works with any VPN, proxy or Tor connection. It detects signs of VPN/proxy/TOR usage from public IP intelligence and tests your connection's leak behaviour regardless of which provider you use.
