Detailed explanation-1: -The domain name system (DNS) is a naming database in which internet domain names are located and translated into Internet Protocol (IP) addresses. The domain name system maps the name people use to locate a website to the IP address that a computer uses to locate that website.
Detailed explanation-2: -The DNS has three components: authoritative servers, recursive servers, and clients (resolvers). A client (resolver) is installed in any computer with TCP/IP software. Generally speaking, a client is any computer with Internet access capability.
Detailed explanation-3: -DNS is the address book of the internet, which performs a simple function of translating domains to IP addresses. One way of looking at it is that it’s a distributed read-heavy database with caches on top.
Detailed explanation-4: -DNS records are stored in authoritative servers. These records provide information about a domain, including its associated IP address for each domain. It is mandatory for all domains to have a specific set of default records.
Detailed explanation-5: -The domain name space is divided into three different sections: generic domains, country domains, and inverse domain.
