Overall, a DNS that is contained in a network greatly facilitates the client computers to be able to access information or interact with another computer or server computer. Why? Because each IP can have a particular name or name of each. Before the existence of DNS, the naming is usually done manually by each client by leveraging the HOSTS file. In addition, in the process of the search domain on a DNS Server, there are two processes: a recursive process contained in the communication between the DNS server and also a process of iterative on the client server.
