DNS Leak Testing

This article explains what a DNS leak is, how to check if your VPN s protecting you from one, and how to confirm that Speedify is keeping your DNS queries private.


What Is a DNS Leak?

When you visit a website, your device sends a DNS request to translate a domain name (like "speedify.com") into an IP (Internet Protocol) address. Normally, when you're connected to a VPN, those DNS requests should travel through the VPN's encrypted tunnel, not your Internet Service Provider (ISP).

A DNS leak happens when those requests bypass the VPN and go directly to your ISP instead. Even if your IP address is hidden, a DNS leak means your ISP can still see which websites you're visiting. A good VPN should prevent this entirely.


Let's Get Started

Step 1

Before connecting to Speedify, go to DNSLeakTest.com with Speedify disabled. The page will display your current public IP address and approximate location. This is your baseline, it shows what websites and services can see about you without any VPN protection.

Step 2

Still on DNSLeakTest.com with Speedify disabled, click Standard test. This will show you the DNS servers your browser is currently using. Make note of the results, these will be from your ISP, and likely tied to your home country.

Step 3

Now open Speedify and connect to a server in a different country, ideally on a different continent. Once connected, reload DNSLeakTest.com. You should see a different public IP address,  one that matches the country your chosen Speedify server is located in.

This confirms that Speedify is routing your internet traffic through its VPN tunnel correctly. In the example below, a server in the Netherlands was selected.

Step 4

With Speedify still connected, click Standard test on DNSLeakTest.com again. Review the list of DNS servers that appear in the results.

If all of the DNS servers shown are located outside your home country, you're protected. Speedify is routing your DNS requests through the VPN tunnel and your ISP cannot see which websites you're visiting.
