DNS Leak Test
Every site you open is looked up by a DNS server first. If those lookups go to your internet provider instead of through your VPN, your provider can see every site you visit. This test shows which DNS servers your browser really uses.
Questions about the DNS Leak Test
What is a DNS leak?
A DNS leak happens when your VPN carries your traffic but the name lookups for the sites you visit still go to another resolver, usually your internet provider.
How does this DNS leak test work?
Your browser looks up a few random names that only our DNS server can answer. Our server records which resolvers asked for them, and those are the resolvers your browser really uses.
How do I fix a DNS leak?
Turn on the DNS protection setting in your VPN app if it has one, turn off any custom DNS or secure DNS setting in your browser, then run the test again.

How Our VPN Test Works
Our comprehensive VPN testing tool performs multiple checks to ensure your VPN is providing the security and privacy you expect. Learn how each test helps identify potential vulnerabilities.
IP Leak Test
Our IP leak test checks if your real IP address is visible to websites despite using a VPN. We verify that your traffic is properly routed through the VPN tunnel, ensuring your actual location and identity remain hidden from websites, advertisers, and potential attackers.
DNS Leak Test
DNS requests can reveal your browsing history even when using a VPN. Our DNS leak test ensures all domain name lookups are securely routed through your VPN provider's DNS servers rather than your ISP's servers, protecting your browsing activity from surveillance.
WebRTC Leak Test
WebRTC technology can bypass VPN protection and expose your real IP address. Our test identifies if your browser's WebRTC implementation is leaking your actual IP address despite your VPN connection, and provides guidance on how to prevent this security vulnerability.
Speed Test
VPNs typically reduce connection speeds due to encryption overhead and routing changes. Our speed test measures your current download and upload speeds while connected to your VPN, allowing you to assess performance impact and determine if your VPN provides sufficient speed for your needs.
