DNS leak test
Every site you open starts with a lookup of its name. See who can read yours.
Testing…
Your DNS lookups
Our test server keeps what it sees in memory for seconds and writes no log.
What your lookups give away
Your device asks for the name of each site before it opens it.
Every site you open
A lookup names the site, even when the page itself is secure.
To whoever answers
Usually your internet provider, which can keep a list of the sites you look up.
Even with a VPN on
Some devices and browsers send lookups around a VPN, straight to a DNS server outside it.
Keep your lookups inside KazaVPN
Connect with KazaVPN and your lookups go through our servers, which keep no record of the sites you open.

Questions about DNS leaks
What is a DNS leak?
When you use a VPN, your lookups should go through it. A DNS leak is a lookup that goes around it, so a DNS server outside the VPN, often your provider's, sees the site you asked for.
How do I fix a DNS leak?
Connect with KazaVPN on the device you are testing and run the test again. If it still finds a leak, turn off any setting that picks its own DNS server, such as secure DNS in your browser, and test once more.
Do you keep my results?
No. Our test server notes which DNS servers asked for the test names only long enough for this page to show you, and writes no log.
