Detailed explanation-1: -The Internet’s DNS system works much like a phone book by managing the mapping between names and numbers. DNS servers translate requests for names into IP addresses, controlling which server an end user will reach when they type a domain name into their web browser. These requests are called queries.
Detailed explanation-2: -DNS is responsible for converting a domain name into an Internet Protocol (or IP) address. For example, ‘CNET.com’ will be converted into something like this: 64.30. 224.118 for identification purposes on the internet. You can convert any Domain name into its equivalent IP address and vice-versa.
Detailed explanation-3: -To enable the use of host names in a network, the Domain Name System (DNS) translates host names to IP addresses. Mapping must be consistent across the network to ensure interoperability. DNS provides the host name-to-IP address mapping through network server hosts called domain name servers .
