At its core, DNS is a hierarchical, decentralized naming system that allows users to access the Internet using domain names instead of cumbersome IP addresses. It acts as an identity management service, converting web users into IP addresses that computers and network devices can understand. This process is essential for the smooth operation of many Internet services, including web browsing, email, and online games.
The Domain Name System is the core of the web, the backbone
that converts human-readable names into machine-readable IP addresses. Its
layered and decentralized structure provides clear and reliable network
navigation. Understanding the DNS system is important for anyone who interacts
with the Internet, whether a user, IT professional, or webmaster.
