NordVPN has implemented a DNS leak protection technology to protect your online activity and privacy in case DNS servers send unencrypted queries outside a secure VPN tunnel.
The Domain Name System (DNS) is responsible for resolving domain names such as “nordvpn.com” into actual IP addresses to connect to. Basically, it translates the long, complex and hard-to-remember numeric names of web servers into human language, and the other way around.
So whenever your computer needs to connect to a certain website, such as when you enter “www.google.com” into your browser, it first contacts a DNS server and requests the unique IP address of that site. This procedure is a crucial piece of how the Internet works.
If you are trying to keep your online activities secure and private with a VPN service, it is extremely important that all the traffic originating from your computer is routed through the VPN network. That includes the above-mentioned DNS requests – they should go through the VPN tunnel to your VPN provider’s DNS servers, rather than those of your ISP.

Should any of your traffic go out through the regular, unencrypted route, it may be intercepted by unauthorized parties such as your ISP or DNS provider. This way, they would be able to see:

When you connect to NordVPN, your device will only use DNS servers operated entirely by NordVPN. This way, you never have to worry about your confidential information leaking and being intercepted by third parties.
You can check for DNS leaks in just a few easy steps:
