DNS Leak Test

Check if your DNS requests are leaking outside your VPN or Tor connection.


How it Works

This tool checks for DNS leaks by detecting your current DNS servers, analyzing DNS request patterns, testing for DNS leaks through multiple methods, verifying DNS over HTTPS (DoH) support, and checking for WebRTC DNS leaks.

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 VPN configuration issues, WebRTC leaks, operating system DNS settings, browser DNS settings, or 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, and enabling DNS-based censorship.

Technical Details

The DNS Leak Test uses several technologies including multiple DNS resolution methods, DNS over HTTPS (DoH) detection, WebRTC DNS leak detection, DNS server fingerprinting, and network path analysis.

The tool checks for DNS server locations, DNS request patterns, DoH support, WebRTC DNS leaks, and VPN DNS leaks.

How to Prevent 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
