Your VPN Might Be Leaking Your IP – Test It Now
🔒 VPN Leak Test
Detect WebRTC leaks, DNS leaks and IP exposure in seconds.
Running all leak tests…
Analyzing WebRTC, DNS and IPv6 exposure.
🔐 What This VPN Leak Test Checks
This tool runs 4 simultaneous tests directly in your browser — no extensions or software required — and returns a Privacy Score from 0 to 100 based on what it finds.
Tests complete in under 6 seconds. Nothing is stored or transmitted to our servers.
🔍 How to read results: Run the test without VPN first — note your IP and ISP. Then connect your VPN and run again. If the same IP or ISP appears, your VPN has a leak.
🔍 Why Does Your IP Leak Even with a VPN?
A VPN leak is a security flaw that occurs when your private information — like your actual IPv4 or IPv6 address — is transmitted outside the encrypted tunnel of your VPN. This means that while your app says "Connected," the websites you visit can still see your true identity and location in real time.
🌐 WebRTC Leaks
WebRTC is a technology built into browsers like Chrome, Edge, and Brave for video calls and peer-to-peer sharing. It is the #1 cause of IP leaks because it often bypasses the VPN tunnel to find the shortest path for data, inadvertently revealing your real local and public IP addresses to any site running a simple JavaScript snippet.
📋 DNS Leaks
A DNS leak happens when your computer sends domain resolution requests to your ISP's servers instead of your VPN's private DNS. This allows your internet provider to log every site you visit — even if the actual content is encrypted — and hand that data to third parties.
🌌 IPv6 Exposure
Most VPNs only tunnel IPv4 traffic. If your network uses IPv6 (common in modern 5G and fiber connections), your device may send IPv6 traffic completely outside the VPN tunnel. If our test detects an active IPv6 address while a VPN is present on IPv4, your true identity could be exposed to any IPv6-capable website.
✅ When Your VPN Is Working Correctly
A properly configured VPN with no leaks delivers real, measurable privacy benefits:
- Your ISP sees nothing — all traffic is encrypted inside the tunnel. Your provider cannot log your browsing history or sell it to data brokers.
- Websites see the VPN server's IP — not yours. Your real location and identity are hidden from trackers, analytics scripts, and advertisers.
- DNS queries are private — resolved by your VPN's own servers, not your ISP. No third party can build a record of the domains you visit.
- Public Wi-Fi is safe — encrypted VPN traffic cannot be intercepted by anyone on the same network, including on hotel, airport, or café connections.
- Geo-restrictions are bypassed — content that is blocked in your country is accessible through the VPN's exit server in another location.
🔴 The Consequences of a Leaking VPN
Using a leaking VPN is like locking your front door but leaving the windows wide open. It exposes you to:
- Identity Tracking: Advertisers link your real IP to your browsing profile and build a shadow identity across every site you visit.
- Regional Blocks: Netflix, Disney+, and other streaming services can detect that you are not actually in the country you selected, blocking access to geo-restricted content.
- ISP Surveillance: Your provider continues to log your full browsing activity for government requests or commercial sale — even while you pay for a VPN.
- Targeted Advertising: Your real location and device fingerprint are tied together, making ad targeting more precise than if you had used no VPN at all.
❓ VPN Leak Test — Frequently Asked Questions
How do I know if my VPN is leaking?
Run this test without your VPN connected and note your IP address and ISP name. Then connect your VPN and run the test again. If you see your original IP address, your ISP name, or a different country in the DNS section, your VPN has a leak.
Can a website see my real IP if I use a VPN?
Normally no — the website only sees the VPN server's IP. However, if your VPN has a WebRTC leak, any website can run a script in your browser to discover your real IP without you knowing. This is why testing matters even when your VPN appears to be working.
What does it mean if my DNS is in a different country than my IP?
It means your DNS queries are not being routed through your VPN tunnel. Even though your browsing traffic may be encrypted, your ISP or a third-party DNS provider can see every domain name you request — effectively logging your browsing history despite your VPN connection.
Is an IPv6 address always dangerous when using a VPN?
Not always — but it is a strong warning sign. If your VPN supports IPv6 tunneling, your IPv6 traffic can be routed securely through the encrypted tunnel. However, if IPv6 is not supported, your device may send IPv6 traffic outside the VPN, bypassing the tunnel and potentially exposing your real connection to IPv6-enabled services.
Why does WebRTC expose my IP even inside a VPN?
WebRTC is designed at the browser level to establish direct peer-to-peer connections. To do this, it needs to gather all available network interfaces on your device — including physical interfaces that are not routed through the VPN. It sends these IPs to STUN servers and exposes them to websites through the JavaScript API, completely bypassing the VPN tunnel.
How do I fix a WebRTC leak without switching VPN?
In Firefox, open about:config and set media.peerconnection.enabled to false. In Chrome and Edge, you need a browser extension that blocks WebRTC IP exposure. The most reliable long-term fix is using a VPN that handles WebRTC blocking at the application level rather than relying on browser settings.
