DNS is often referred to as the internet's phone book because it converts easy-to-remember hostnames like www.google.com , to IP addresses like 216.58.217.46 .

For example, in the domain name sub.secondary.com, "com" is the top-level domain, "secondary" identifies the secondary domain name (commonly a site hosted by an organization and/or business), and "sub" identifies a subdomain within the larger network. This entire DNS domain structure is called the DNS namespace.

However, people refer to use names instead of address. Therefore, we need a system that can map a name to an address and conversely an address to name. In TCP/IP, this is the domain name system. DNS in the Internet: DNS is protocol that can be used in different platforms. Domain name space is divided into three categories. What Is A Domain Name? A web domain name is a sequence of letters and/or numbers/hyphens separated by one or more periods (".") that act as a pointer to a unique numerical address (IP) on a computer network such as the Internet. That address may host publicly available content (e.g a web site), or may be a private intranet.

Domain: While the term "domain" is often used synonymously with " domain name ," it also has a definition specific to local networks. The Domain Name Structure and Domain Name System were developed to organise and find the IP addresses of Computers on large distributed networks. Before the domain name structure was developed computer names and IP addresses were mapped using a flat list and stored in a simple text file called the hosts file.

In an operating system, an example of namespace is a directory. Each name in a directory uniquely identifies one file or subdirectory, but one file may have the same name multiple times.

As a rule, names in a namespace cannot have more than one meaning; that is, different meanings cannot share the same name in the same namespace. The Domain Name System (DNS), defined in RFCs 1034 and 1035, is used on the Internet to provide a standard naming convention for locating IP-based computers. On the Internet, before the implementation of DNS, the use of names to locate resources on TCP/IP networks was supported by a file called Hosts. Network administrators entered names and IP addresses into Hosts, and computers used the file
