What is Domain Name System (DNS) ?

The Domain Name System (DNS) is a hierarchical decentralized naming system for computers, services, or any resource connected to the Internet or a private network.

The Domain Name System or DNS is a service that translates human-readable website addresses into the IP addresses required for connecting to the server. It is a hierarchical system with 13 root servers around the world.

DNS servers are responsible for querying and resolving domain names to IP addresses. When you type any  URL in your browser, it queries your ISP's DNS server, then queries other DNS servers until it finds an authoritative answer. If you have an ISP that doesn't provide default DNS settings, you can configure them manually on your device.
