Checking your connection for potential leaks.
Quick Answer
Use our free IP leak test tool above to instantly check for VPN leaks. The test detects your visible IP address, checks for WebRTC leaks that expose your real IP, and verifies your DNS configuration. If leaks are found, we recommend using a VPN with built-in leak protection.
What This Tool Tests
Detects your visible IP address and geolocation. If you're using a VPN, this should show the VPN server's IP, not your real one.
Checks if your browser's WebRTC feature is exposing your real IP address, a common vulnerability even when using a VPN.
Identifies which DNS servers are handling your requests. Secure VPNs route DNS through their own servers.
How to Fix VPN Leaks
Use a Quality VPN
Premium VPNs include built-in leak protection for DNS, WebRTC, and IPv6.
Enable Kill Switch
A kill switch blocks internet if VPN disconnects, preventing accidental exposure.
Disable WebRTC
Use browser extensions or VPN apps that block WebRTC leaks automatically.
Use VPN's DNS Servers
Configure your device to use your VPN provider's DNS servers for all requests.
Disable IPv6
If your VPN doesn't support IPv6, disable it to prevent traffic from bypassing the tunnel.
Test Regularly
Check for leaks after updates, server changes, or when connecting from new networks.
VPNs with Built-in Leak Protection
These VPNs include comprehensive leak protection features out of the box.
Frequently Asked Questions
What is an IP leak?
An IP leak occurs when your real IP address is exposed despite using a VPN. This can happen through DNS requests, WebRTC connections, or IPv6 traffic that bypasses your VPN tunnel, compromising your privacy and anonymity online.
What is a WebRTC leak?
WebRTC (Web Real-Time Communication) is a browser feature for video calls and file sharing. It can leak your real IP address even when using a VPN because it may bypass the VPN tunnel to establish peer-to-peer connections. Quality VPNs include WebRTC leak protection.
What is a DNS leak?
A DNS leak happens when your DNS queries are sent to your ISP's servers instead of through your VPN's encrypted tunnel. This exposes the websites you visit to your ISP, even when connected to a VPN.
How do I fix VPN leaks?
To fix VPN leaks: 1) Use a VPN with built-in leak protection, 2) Enable the VPN's kill switch feature, 3) Disable WebRTC in your browser or use a VPN browser extension, 4) Ensure IPv6 is disabled or routed through the VPN, 5) Use the VPN's own DNS servers.
How often should I test for VPN leaks?
You should test for leaks when you first set up your VPN, after any VPN updates, when switching servers, and periodically (monthly) to ensure continued protection. Also test after browser updates as they may reset WebRTC settings.
Can a free VPN protect against leaks?
Free VPNs often lack advanced leak protection features like kill switches, DNS leak protection, and WebRTC blocking. Premium VPNs typically offer comprehensive leak protection and regular security audits to ensure your privacy.
This tool runs entirely in your browser. We do not store your IP address or any test results. All WebRTC tests are performed locally without sending data to our servers.
