DNS Leak Test
Check if your DNS queries are leaking outside your VPN or proxy
What is a DNS leak?
When you use a VPN or proxy, all your internet traffic — including DNS queries — should go through the encrypted tunnel. A DNS leak happens when your DNS requests bypass the tunnel and are sent directly to your ISP's DNS servers instead.
This means your ISP (or anyone monitoring your connection) can see which websites you're visiting — even if the rest of your traffic is encrypted. DNS leaks effectively defeat the privacy benefits of a VPN.
How this test works
This test makes requests to multiple independent services and compares the IP addresses they see. If all services see the same IP, your connection appears consistent. If different IPs are detected, some requests may be taking different network paths — a potential indicator of a DNS leak.
- Connect to multiple test endpoints
- Compare responding IPs across services
- Flag inconsistencies as potential leaks
