Understanding Your DNS Leak Test Results
When you browse the internet, your computer uses DNS (Domain Name System) servers to translate human-readable website names (like www.example.com) into numerical IP addresses that computers use to connect to each other.
The list above, under "Your DNS requests originate from...", shows the IP addresses of the DNS servers that were detected handling these translation requests for your connection during this test.
Why this matters: The operators of these DNS servers can see which websites you are looking up. While many DNS providers have strong privacy policies, this information could potentially be logged and associated with your public IP address (shown in the "Your Public IP Information" section). This doesn't necessarily mean they are logging your activity, but the capability exists.
If you are using a VPN: Ideally, all the DNS servers listed should belong to your VPN provider. If you see any DNS servers from your regular Internet Service Provider (ISP), or other unexpected providers, it's called a "DNS leak." This indicates that some of your DNS queries might not be going through the VPN's encrypted tunnel, potentially revealing parts of your browsing activity.
If you are NOT using a VPN: It's normal to see DNS servers belonging to your Internet Service Provider (ISP).
This test helps you understand where your DNS queries are being sent, allowing you to assess your connection's privacy.
🧠 What Is a DNS Leak?
Every time you open a website, your device first asks a DNS (Domain Name System) server for directions. Think of it like asking a digital phone book, “Where can I find this website?” This happens not just when visiting pages, but also when loading images, ads, and downloading files.
But here's the catch: if you're not using a privacy-friendly DNS setup, all of those requests are visible to your DNS provider. That means your browsing habits — even on encrypted websites — can be exposed. This is what's known as a DNS leak.
👁️ Why it matters:
Even if you're using a VPN, a DNS leak can quietly give away what you're doing online.
