The name that is given to identify a website is known as the domain name. These names are formed by the Domain Name System’s (DNS) rules and regulations. These will give the website an identification label.
These domain names are organized into sub-domains on two different levels. The top level domains are the first level set and are made up of generic top level domains (gTLDs), these make up net, com, and org. The country code top levels (ccTLDs) are also made up here. Under the DNS hierarchy top level domains are the levels that are open for use by end users. The end user may wish to use these for local area network connection, website running or accessing the resources of the Internet publicly. A domain name registrar will sell these domain name services to the public.
The individual Internet website will use host names or host identifiers. These will serve as labels for the domain system’s name. In the Uniform Resource Locator (URL) the host name will look like a component for the Internet resource.
The identification labels are used by the name of the domain for showing the proof of ownership or resource control. The realm identifiers that are used in the Session Initiation Protocol (SIP) are an example. The Session Initiation Protocol is when the DomainKeys are used as verification of the Domain Name System for the email system. These is also used for other Uniform Resource Identifiers.
Names that are easy to recognize and to remember should be used. These makes for it to be easily moved to a physical address in the topology of a network or intranet. This involves changing the IP address of the resource and translating that IP address to the domain name.
The domain registrant has the right to use to the domain exclusively, but not legal ownership of the domain name. There are now 196 million domain names that are actively registered.
