DNS (Domain Name System) is a hierarchical decentralized naming system for computers, services, or any resource connected to the internet or a private network. It translates domain names, which are human-readable identifiers, into numerical IP addresses required for locating and identifying these resources. DNS operates through a distributed database system, with various servers around the world containing portions of the overall DNS namespace.

INSTALLATION OF DNS SERVER IN CENTOS LINUX: https://sweshi.com/developer.sweshi.com/DNS%20Server%20configuration%20Centos%20Linux/Configure%20DNS%20(named)%20in%20Centos%209%20-%20Part%202%20-%20Installation%20of%20bind-utils%20named%20and%20nslookup.php

In the context of CentOS (a Linux distribution), "named" refers to BIND (Berkeley Internet Name Domain), which is the most widely used DNS software on the internet. CentOS, being a popular Linux distribution used for servers, often uses BIND (named) for its DNS needs. BIND provides the tools necessary to set up and maintain a DNS server on CentOS, allowing it to resolve domain names to IP addresses and vice versa.

Setting up a DNS server on CentOS typically involves installing the BIND package and configuring the named service through its configuration files. Administrators can define zones, which are sections of the DNS namespace for which the CentOS server is authoritative. These zones can include domain names for which the CentOS server is responsible for providing DNS information.
