The Domain Name System (DNS) is a system that translates human-readable domain names, like swindx.com, into numerical IP addresses that computers use to locate websites and services on the internet.
When someone visits swindx.com, DNS finds the matching IP address so their browser can connect to the correct server.
DNS acts like the internet’s phone book. Instead of remembering an IP address like 192.0.2.1, users can type a domain name.
