How it works
What is a DNS leak?

Every time you visit a site, your device asks a DNS server to translate the name into an address. If those queries escape the VPN tunnel and go to your ISP's resolver, that's a DNS leak — your ISP sees every site you look up, even on a VPN. Toggle below to see the difference.

The fix
How LunoVPN stops DNS leaks

LunoVPN actively performs DNS leak protection on every connection — so your lookups stay private, automatically.

Queries inside the tunnel

All DNS requests are forced through the encrypted tunnel — they never travel over your ISP's network in the clear.

Private DNS resolvers

LunoVPN runs its own no-log DNS servers, so your queries are resolved by us — never handed to your ISP or a public provider.

IPv6 & WebRTC covered

Alongside DNS, we block IPv6 and WebRTC leaks and back it with a kill switch — closing every common leak path.

FAQ
DNS leak questions
What is a DNS leak?
A DNS leak happens when your DNS queries — the lookups that turn site names into addresses — escape the VPN tunnel and reach your ISP's resolver, revealing the sites you visit even while connected to a VPN.
Why is a DNS leak dangerous?
It defeats much of the point of a VPN: your ISP (and anyone with access to it) can log every domain you look up, building a record of your browsing despite the encrypted connection.
How does LunoVPN prevent DNS leaks?
LunoVPN routes every DNS query through the encrypted tunnel to its own private, no-log resolvers. Because queries never leave the tunnel, third parties can't see or log them.
How often should I test for leaks?
It's good practice to test whenever you connect on a new network or after changing settings. With LunoVPN's always-on protection, you should consistently see only our private DNS.
My test shows a leak — what now?
Connect to LunoVPN (or reconnect), make sure the app is up to date, and run the test again. If a leak persists, our 24/7 support can help right away.
