What are DNS leaks and how do they threaten your privacy?

To start off, the DNS, or the Domain Name System, is responsible for converting domain names into IP addresses.

For example, whenever you enter “nordvpn.com” into your browser, it first contacts a DNS server and requests the unique IP address of the site.

When you’re browsing without VPN, such requests usually go through DNS servers owned by your Internet service provider. This way, your ISP can monitor your online activity.

When you’re browsing with VPN, DNS requests are routed through DNS servers owned by your VPN provider, such as NordVPN, so that your ISP can’t see what you do on the Internet.

So when do DNS leaks happen?

Even if you’re connected to VPN, there is a risk your system will revert to the default DNS server. This may happen if your VPN is configured improperly, or the VPN service you’re using doesn’t have its own DNS servers.

Basically, a DNS leak means that your internet traffic is ‘leaking’ outside the secure VPN tunnel – that is, your private online data is exposed.

The best way to avoid this is to use a VPN service that owns its DNS servers and offers adequate protection from leaks.

NordVPN has implemented a DNS leak protection technology to prevent any unencrypted queries going outside the secure VPN tunnel. So with NordVPN up and running, you can keep calm – your private data will stay private.
