The DNS (Domain Name System) is what translates hostnames (such as www.vyprvpn.com) into the IP address that your computer reads. Commonly, internet users will rely on their ISP's provided DNS servers or a 3rd party DNS. Many of which configured to log activity and enforce censorship.
To get around censorship and DNS "Man-in-the-middle" attacks, we have VyprDNS. VyprDNS is our own proprietary DNS. It is designed to be encrypted and not log your activity. The purpose and benefit is it allows you to surf the web, reaching desired websites without being tracked and not giving away that you're connected through a VPN.
We setup VyprDNS in such a way that prevents your DNS query from being associated with your activity on VyprVPN. Doing this prevents organizations from interfering by restricting the DNS. This is done using a DNS relay system.
If you use a site to check for DNS leaks, you will see the last server in the DNS relay chain, which typically does not identify itself with VyprVPN services. This is good because the DNS is not identified as coming from VyprVPN, which is the intended goal.
We do have a more detailed article regarding VyprDNS and you are invited to give it a look!
