What is a DNS Leak?
A DNS leak occurs when your DNS requests bypass your VPN or Tor connection,
potentially exposing your browsing activity to your ISP or other third parties.
This can happen due to various reasons, including:
- VPN configuration issues
- WebRTC leaks
- Operating system DNS settings
- Browser DNS settings
- Network misconfiguration
Why Check for DNS Leaks?
DNS leaks can compromise your privacy by:
- Revealing your browsing history to your ISP
- Bypassing VPN protection
- Exposing your real location
- Allowing DNS-based tracking
- Enabling DNS-based censorship
Understanding the Test Results
The test analyzes several aspects of your DNS configuration:
- Current DNS servers
- DNS request patterns
- DoH support and usage
- WebRTC DNS leaks
- VPN DNS leaks
How to Prevent DNS Leaks
To protect against DNS leaks:
- Use a VPN with DNS leak protection
- Enable DNS over HTTPS (DoH)
- Configure your VPN to handle DNS requests
- Disable WebRTC in your browser
- Use a privacy-focused DNS provider
How it Works
This tool checks for DNS leaks by:
1. Detecting your current DNS servers
2. Analyzing DNS request patterns
3. Testing for DNS leaks through multiple methods
4. Verifying DNS over HTTPS (DoH) support
5. Checking for WebRTC DNS leaks
The test is performed securely and doesn't store any of your data.
