Domain Name is a symbolic representation of an object on the Internet from a set of all possible potential names in a particular context and has a meaning within this context. This infrastructure comprises of several integrated components including Domain Names, IP addresses, Resource Records, Servers, Resolvers and Communication Protocols managed by structured governing bodies.
The DNS infrastructure is made up of computing and communication entities that are geographically distributed throughout the world. The domain name system is the distributed database responsible for the domain name-to-IP address conversion, while the domain name service, as the name implies, is the service offered by this system. The abbreviation DNS is used to describe two related things: the Domain Name System and the Domain Name Service. The purpose of the DNS as depicted by figure 1 is quite simple: it is a service running on different computers that looks up domain names and resolves them into an IP address so that clients that only know the domain names of the servers and not their IP addresses can communicate with them. Another benefit of using DNS is that it allows names to be separated from locations thus allowing services and devices to be moved to different network locations, without the need for name change and without any effect on the way users visit or use that website. that are available on the server computer by specifying a unique Uniform Resource Locator (URL) which includes a protocol like HTTP, FTP, etc. Users can also request resources like Webpages, mailboxes, files, etc. In order to make the identification of destination computer system simple and mnemonic, a Domain Name System (DNS) has been developed which enables to use globally unique easy-to-remember names called domain names for Webpages and mailboxes, rather than long numbers or codes (IP addresses), e.g. when a request for a Webpage is sent from a client computer system to a Webserver, the client computer includes the IP address of the Webserver. Computers on the Internet use IP addresses to route traffic and establish connections among themselves.
An Internet Protocol Address is the numerical address of the form 192.0.43.10 (IP Version 4) or 2001:500:88:200:0:0:0:10 (IP Version 6) by which a location in the Internet is identified.
