VPN detector test
This VPN detector checks your connection the way streaming services, banks and online shops do. It gives you a score from 0 to 100 for how easy it is to tell that you are using a VPN or proxy, and shows each signal that gives you away.
How websites detect a VPN
- IP address type. VPN servers live in data centers. Sites check your IP against lists of hosting and VPN networks. This is the strongest signal and the hardest to hide.
- Time zone. Your browser reports its time zone. If it says New York while your IP is in Germany, that mismatch suggests a VPN.
- Browser language. A language setting for one country with an IP in another is a weak hint on its own, but it adds up.
- WebRTC. If WebRTC shows a different public IP from your connection, the site can see both your VPN IP and your real one.
- IPv6. An IPv4 address on a VPN network and an IPv6 address from a home ISP gives the tunnel away.
- Proxy headers. Some proxies announce themselves by adding headers to every request.
How to read your score
0 to 19, low: your connection looks like a normal home or mobile user. 20 to 49, medium: some signals point to a VPN and strict sites may flag you. 50 to 100, high: websites can easily tell you use a VPN or proxy.
If you are not using a VPN, a low score is what you should see. Run the test again with your VPN on to see the difference.
How to make your VPN harder to detect
- Match your time zone to the server. Pick a VPN server in your own country, or change your device’s time zone to match the server location.
- Fix leaks first. Stop WebRTC and IPv6 leaks with the IP leak test and our WebRTC guide.
- Use obfuscated or dedicated IP servers. Many VPNs offer servers that are not on public VPN lists, or a dedicated IP that only you use.
- Try another server. Some IP ranges are blocked more often than others. Switching servers can help.
Who uses VPN detection?
Many kinds of websites check whether visitors use a VPN, for different reasons:
- Streaming services must show the catalogue licensed for your country, so they block known VPN addresses.
- Banks and payment services treat VPN traffic as higher risk and may ask for extra verification.
- Online shops check VPN use to fight fraud and to show regional prices.
- Games and gambling sites often have country rules and block VPNs to enforce them.
- Forums and social sites may limit sign-ups from VPN addresses to fight spam.
VPN detector vs VPN leak test
This VPN detector answers “can websites tell that I use a VPN?”. It is useful when a site blocks you or asks for extra checks. Our VPN leak test answers a different question: “can websites see my real IP?”. A VPN can be easy to detect and still protect you perfectly. Run both to get the full picture.
FAQ
Is using a VPN detectable?
Usually, yes. Most VPN IPs are known data center addresses. A site can see that you use a VPN even though it cannot see your real IP or what you do.
Why does Netflix or my bank say I use a VPN?
They check your IP against VPN lists and look at signals like your time zone. Use the steps above or ask your VPN provider for a streaming or dedicated IP server.
Does a high score mean my VPN is not working?
No. The score shows how easy it is to tell that you use a VPN, not whether it protects you. Use the VPN leak test to check that your real IP stays hidden.
Do you store my results?
No. The test runs in your browser and we do not keep a record of your IP or score.
Can a website see which VPN I use?
Sometimes. IP lookups often name the hosting company or VPN provider behind an address. Websites cannot see your account or what you do inside the tunnel.
