The term DNS stands for Domain Name System. The DNS server links the domain name of a web site to the IP address of a server connected to the Internet. In other words, its role is to translate a humanly understandable address into a numerical IP address that can be used by computers and networks.
If you are not using a VPN (which usually already offers a secure DNS), you can decide to use a specific DNS instead of your ISP’s.
