DNS Leak Test

This detection checks whether your VPN is actually keeping your DNS requests private by analyzing your visible IP location and the DNS servers handling your queries. If your DNS queries are leaking, websites (or your ISP) can still see where you’re going online, even if your VPN shows a different IP.

DNS Leak Test - Real DNS Privacy & Security Check

🔒 DNS Leak Test

Real DNS leak detection using actual IP geolocation and DNS resolution analysis. Check if your VPN is properly protecting your DNS queries.

🛡️ DNS Privacy & Security Guide

Understanding DNS Leaks

DNS leaks occur when your device bypasses your VPN's DNS servers and uses your ISP's DNS instead, potentially exposing your browsing activity.

Common Leak Causes:

  • • VPN software not configured properly
  • • IPv6 traffic bypassing VPN tunnel
  • • DNS cache using old ISP settings
  • • Transparent DNS proxies by ISP
  • • Split tunneling configurations

Prevention & Solutions:

  • • Use VPN with DNS leak protection
  • • Configure secure DNS: 1.1.1.1, 8.8.8.8, 9.9.9.9
  • • Disable IPv6 if VPN doesn't support it
  • • Enable DNS over HTTPS (DoH) in browser
  • • Use VPN kill switch feature
  • • Flush DNS cache after VPN connection

Recommended DNS Providers:

  • • Cloudflare: 1.1.1.1 (Privacy-focused)
  • • Quad9: 9.9.9.9 (Security-focused)
  • • Google: 8.8.8.8 (Fast, reliable)

🔧 How This Test Works

Real Detection Methods

1. IP Geolocation: Uses multiple IP geolocation APIs to determine your real location and ISP information.

2. DNS Resolution Analysis: Makes DNS queries to special detection domains that log the resolver's IP address.

3. Location Comparison: Compares detected DNS server locations with your IP location and expected VPN location.

4. ISP Detection: Identifies if DNS queries are going to your ISP's servers instead of VPN DNS.

Accuracy & Limitations

High Accuracy: Uses real geolocation data and actual DNS resolution to provide accurate results.

Browser Limitations: Some advanced DNS configurations may not be detectable through browser-based testing.

Network Complexity: Corporate firewalls and complex routing may affect detection accuracy.

Real-time Testing: Results reflect your current network state and may change with different connections.
