DNS servers (or Domain Name System) is what the internet use to find the website you are trying to visit. It is like the Yellow Pages of the internet which translates the website you are trying to visit (For example vilfo.com) into the IP-address where the website is located.
Vilfo will seamlessly assign you a DNS address from either your ISP (if not connected to a VPN), or one provided by your VPN provider (if connected to a VPN) to prevent a DNS leak. It is therefore recommended that you have Vilfo set as the DNS server on your devices — even if doing so is completely voluntary.
Note! If you do not wish to use the DNS address provided by your ISP, Vilfo also offers the option to manually change the DNS used by Vilfo over WAN.
