Is My VPN Leaking?

Check for IP, DNS, and WebRTC leaks in your VPN connection

VPN Leak Test

Test Your VPN Security

This tool checks for IP, DNS, and WebRTC leaks that could expose your real identity while using a VPN.

-

IP Address Leak

Checks if your real IP is exposed despite using a VPN.

-

DNS Leak

Checks if DNS queries go through your VPN or leak to your ISP.

-

WebRTC Leak

Checks if WebRTC reveals your real local or public IP address.

How VPN leak testing works

IP Leak Test: Checks your visible public IP address. If your VPN is working properly, this should show the VPN server's IP and location, not your real one.

DNS Leak Test: Verifies which DNS server is resolving your domain lookups. Even with a VPN, your DNS queries might still go through your ISP's servers, revealing the websites you visit.

WebRTC Leak Test: WebRTC is a browser API used for real-time communication. It can sometimes bypass VPN tunnels and reveal your real public or local IP address through STUN server requests.

Frequently Asked Questions

What is a VPN leak?
A VPN leak occurs when your real IP address, DNS queries, or WebRTC data bypasses the VPN tunnel and is exposed to websites. This defeats the purpose of using a VPN for privacy, as sites can see your actual location and identity.
What are the types of VPN leaks?
There are three main types: IP leaks (your real IP is visible despite the VPN), DNS leaks (your DNS queries go to your ISP instead of the VPN's DNS), and WebRTC leaks (browser WebRTC reveals your real IP through peer-to-peer connections).
How do I fix a WebRTC leak?
You can disable WebRTC in your browser settings or use extensions like WebRTC Leak Prevent. In Firefox, set 'media.peerconnection.enabled' to false in about:config. Most reputable VPN apps now include WebRTC leak protection.
How do I fix a DNS leak?
Use your VPN provider's DNS servers (most VPN apps do this automatically). Enable the DNS leak protection setting in your VPN app. As a fallback, manually set your DNS to a privacy-focused provider like 1.1.1.1 or 9.9.9.9.
Should I run this test with and without my VPN?
Yes. First test without VPN to see your real IP and DNS. Then connect to your VPN and run the test again. Your IP and DNS should change completely. If any results match your real info from the first test, you have a leak.
