Domain Name System

The Domain Name System (DNS) is a hierarchical system that translates human-readable domain names (such as www.le4f.agency) into numerical IP addresses (such as 192.168.0.1) that computers use to communicate with one another over the internet. The DNS is like a phone book for the internet, allowing users to access websites using easy-to-remember names rather than a series of numbers. DNS records are maintained by domain name registrars and can be edited to direct a domain name to a specific IP address.
