DNS (Domain Name System) is a hierarchical and decentralized naming system for computers, services, or other resources connected to the Internet or a private network. It associates various information with domain names assigned to each of the connected devices using a distributed database system. The primary purpose of DNS is to translate human-readable domain names into numerical IP addresses that computers use to locate and communicate with each other.
DNS Basics
DNS is built on a hierarchical structure consisting of a root zone, top-level domains (TLDs), second-level domains (SLDs), and hostnames. The root zone is the starting point for all DNS queries, and it points to the TLDs, which in turn point to the SLDs. Hostnames are the final level in the hierarchy and represent specific devices or services within a domain.
