DNS leak test

Is your DNS leaking?

A leaking DNS can expose every website you visit — even while connected to a VPN. This test runs 6 queries through your browser to see what your system actually resolves.

Is your DNS leaking?
Check if your DNS queries are secure

Browser-based check. Results depend on your network, extensions and system DNS settings.

What these results mean

What is a DNS leak?

When a device bypasses the VPN tunnel and sends DNS queries directly to your ISP or another third-party resolver. They see every site you visit even though the rest of your traffic is encrypted.

Why it matters

A DNS leak defeats the main point of using a VPN for privacy. Your browsing history can still be logged and sold by your ISP, or monitored on public Wi-Fi.

How to fix it

Use a VPN with built-in DNS leak protection (like MegaV). Or manually set your DNS to an encrypted resolver (1.1.1.1, 8.8.8.8, or MegaV DNS) in your OS settings.

Frequently asked questions

DNS leaks — what and why.

What causes a DNS leak?
Most commonly an improperly configured VPN app, a leaky router, IPv6 traffic routed outside the tunnel, or SmartDNS services that split-route queries.
Does MegaV leak DNS?
No. MegaV forces every DNS query through our own encrypted resolver whenever the VPN is active, on every platform — no way to leak even if you misconfigure.
Can DNS leak happen on mobile?
Yes. iOS and Android occasionally route some system queries outside the VPN tunnel — called 'captive portal checks' or 'connectivity probes'. MegaV blocks these.
Does incognito mode prevent DNS leaks?
No. Incognito only clears your local browser history. DNS queries still happen at the OS level and can leak regardless of browser mode.
What IPs should I see?
If the test shows only VPN server IPs — you're safe. If you see your ISP or other providers, your DNS is leaking. Ideally all resolvers are owned by one provider (your VPN).
Is the test 100% accurate?
Browser-based tests detect the most common leaks but can miss system-level ones (smart-TV, IoT). For full coverage, test from each device you use.
Zero DNS leaks

Guaranteed leak-free DNS

MegaV routes every query through our encrypted resolver. If a leak ever happens, the kill-switch blocks traffic until the tunnel recovers.
