DNS Leak Test
See which network and edge location is handling your requests — a quick way to spot when your DNS or traffic is escaping your VPN tunnel.
🕳️ What's a DNS leak
When your VPN routes traffic but DNS lookups still go to your ISP's resolver, sites you visit can be logged by your ISP — defeating much of the VPN's privacy.
🔧 Fix leaks
- Enable your VPN's DNS leak protection
- Use encrypted DNS (DoH/DoT) like 1.1.1.1 or 9.9.9.9
- Re-run after connecting your VPN and compare
ℹ️ Browser limits
Browsers can't enumerate every resolver a true desktop leak test sees. This shows the edge/colo and network serving you — enough to catch most VPN routing problems.
Frequently Asked Questions
How do I know if I have a leak?
Run this with your VPN OFF and note the network/country. Connect the VPN and run again — the values should change to the VPN's location. If they still show your real ISP, you have a leak.
Why isn't this as thorough as desktop leak testers?
Desktop apps can issue raw DNS queries to many test domains; browsers can't. This catches the common cases by showing the network and edge actually serving you.
