Detailed explanation-1: -The Domain Name System (DNS) Server is a server that is specifically used for matching website hostnames (like example.com)to their corresponding Internet Protocol or IP addresses. The DNS server contains a database of public IP addresses and their corresponding domain names.

Detailed explanation-2: -DNS uses certain records for resolving a domain name to an IP address. To determine a host name based on the IP address, DNS uses the reverse lookup. For resolving IPv4 addresses, DNS uses the A record. The A record can store a 32-bit address and can resolve IPv4 addresses.

Detailed explanation-3: -A DNS resolver, also called a recursive resolver, is a server designed to receive DNS queries from web browsers and other applications. The resolver receives a hostname-for example, www.example.com-and is responsible for tracking down the IP address for that hostname.

Detailed explanation-4: -A/AAAA DNS records An A Record, or AAAA record, is used to point a hostname at an IP address. This record type can be used to point your domain name at your web host or for creating subdomains that point directly to an IP address.

Detailed explanation-5: -Address Mapping record (A Record)-also known as a DNS host record, stores a hostname and its corresponding IPv4 address.
