How to test your VPN
- Run this test once with the VPN off. Note your IP address and provider.
- Connect the VPN and click Test again. The IP address, location and network should all change to the VPN server's.
- Look at the checks. Every red or orange line is a way websites can still see your real connection or tell that you're on a VPN.
- Repeat after changing VPN settings, switching servers or updating the app.
What each check means
- VPN or proxy: whether your IP belongs to a datacenter or VPN network. If it's your normal provider, the VPN isn't carrying this browser's traffic.
- WebRTC leak: browsers can reveal your real IP to websites through WebRTC, even with a VPN on.
- DNS leak: your DNS lookups (the names of every site you open) go to your internet provider instead of through the VPN.
- IPv6 leak: many VPNs only carry IPv4. If your connection also has IPv6, that traffic goes around the VPN with your real address.
- Time zone and language: a device set to one country while its IP is in another is a common sign of a VPN.
- VPN detectable: your VPN's IP is on public lists of VPN and proxy servers, which streaming sites and banks use to block them.
How to fix a leaking VPN
- WebRTC: turn on your VPN app's WebRTC protection or install its browser extension, or disable WebRTC in your browser.
- DNS: turn on DNS leak protection in the VPN app, or set your VPN's own DNS servers. On Windows, switch off Smart Multi-Homed Name Resolution if leaks continue.
- IPv6: turn on IPv6 leak protection in the VPN app, or switch IPv6 off on your network adapter if the VPN doesn't support it.
- No VPN detected: check that the VPN is connected, its kill switch is on, and split tunnelling doesn't exclude your browser. Proxy apps like Clash in system-proxy mode often miss traffic; TUN mode covers everything.
- Time zone: set your device clock to the VPN country's time zone, or use a browser profile that matches it.
Why streaming sites still block your VPN
Even a VPN with no leaks uses datacenter IP addresses, and Netflix, BBC iPlayer, banks and some AI services keep lists of them. If the VPN detectable check is orange, try another server, a VPN with dedicated streaming servers, or a dedicated or residential IP.
Questions
How do I know if my VPN is working?
Run this test with the VPN on. If the VPN or proxy check is green and shows the VPN provider instead of your internet provider, the VPN is carrying your traffic. If the WebRTC, DNS and IPv6 checks are green too, it isn't leaking.
What is a good privacy score?
100% means no leaks and nothing that gives the VPN away. Leaks cost the most points because they expose your real connection. Scores above 80% with only time zone or language warnings are fine for most people.
Is this VPN test free?
Yes. It runs in your browser, needs no sign-up, and we don't store your IP address or results.
Why does the test say no VPN detected when my VPN is on?
Your browser's traffic isn't going through the VPN. Common causes: the VPN is still connecting, split tunnelling excludes the browser, a browser extension proxy is off, or a proxy app is in system-proxy mode and the browser ignores it.
Can websites tell I'm using a VPN?
Often, yes. VPN servers use datacenter IP addresses that appear on public lists, and a time zone or language that doesn't fit the IP's country is another sign. That's legal and usually harmless, but streaming services and some sites block VPN users.
Does a VPN hide my location?
It hides your IP address, which is how websites usually locate you. Sites can still ask for your GPS location with a permission prompt, and your time zone can hint at your real region.
Guides
- What is an IP address?
An IP address is the number that tells the internet where to send data meant for you. Here's what it looks like, the different kinds, and what yours says about you.
- How to find your IP address
Your public IP takes one click to find. Your private IP depends on the device. Here are the exact steps for each.
- IPv4 vs IPv6: what's the difference?
IPv6 replaces IPv4 because the world ran out of addresses. Here's how the two compare, how to tell which you're using, and why IPv6 matters if you use a VPN.
- What is a DNS leak and how do you fix it?
Even with a VPN on, your device may still ask your internet provider for every website you visit. That's a DNS leak. Here's how to spot one and stop it.
