DNS Leak Test
This tool checks which DNS servers are actually handling your DNS queries. If you're using a VPN, your DNS requests should go through the VPN's DNS servers. If they don't, you have a DNS leak.
What is a DNS Leak?
When you use a VPN, all your internet traffic โ including DNS queries โ should be routed through the VPN tunnel. A DNS leak occurs when your DNS queries bypass the VPN and are sent to your ISP's DNS servers instead.
- No leak: Only your VPN provider's DNS servers appear
- Possible leak: Your ISP's DNS or unexpected DNS servers appear
How this test works
We generate unique domain names and ask your browser to resolve them. Our authoritative DNS server records which DNS resolvers queried those domains โ revealing your actual DNS path.
