A DNS leak test is a crucial tool for ensuring your online privacy and security. When using a VPN, it is vital to confirm that DNS queries are also protected. DNS leaks can reveal information such as the websites you visit by exposing DNS requests to your ISP or third parties. Running a DNS leak test allows you to verify that your DNS queries are routed securely, preventing unintentional exposure of your browsing activity.

How do I read my DNS leak test results? Does seeing multiple DNS servers mean I'm leaking?

Not necessarily. Some networks legitimately use several resolvers at once. What matters is who operates them and which region they're in — and whether that lines up with your current network exit. If an address shows up that you never configured and it belongs to your local broadband provider, that's pretty much a confirmed leak.

What's the difference between a DNS leak and an IP leak?

They expose different things. A DNS leak reveals which domains you're looking up and who resolves them for you, which can hint at your approximate location. An IP leak exposes your actual public IP address. Neither one covers the other, so the DNS test and the WebRTC test need to be run separately — passing one doesn't mean you're clean.

I changed my network — why does the DNS test still show my old provider?

Usually one of three things: your OS or browser is still holding cached DNS entries, a static DNS is manually set on your network adapter, or your browser has secure DNS (DoH) switched on and is resolving through its own channel. Flush the DNS cache, reconnect, and test again. If only one browser looks wrong, check its DoH settings first.

Different browsers on the same computer give different DNS results — is that normal?

How often should I run a DNS leak test? When do I definitely need to retest?
