Authoritative name servers are responsible for their particular domains which in turn assigns other authoritative name servers designated for their sub domains. This makes the Australian Domain Name System distributed and fault tolerant which has helped avoid the need meant for a single central register towards being continually being consulted and updated. The Australian Domain Name System in general also stores other types of data such as the mail servers list which accepts email for a given web domain. DNS is an essential part of the Internets functionality by providing a worldwide dispersed keyword based redirection service.
A number of other identifiers could potentially use DNS such as RFID tags, International characters in host names and email addresses, UPC codes and the likes. The Australian Domain Name System defines the technical aspects of the functionality of this file service. It also defines the DNS protocol as part of the IP suite. The DNS Protocol gives a detailed specification of the communication exchange and the data structures used in Australian DNS. An Australian Domain name is an ID label which defines a realm of administrative authority, control or autonomy on the internet in the country, based on this Domain Name System.
An Australian Domain name is used in various application specific names, networking contexts and addressing purposes. It is organized in sub domain levels of the DNS root domain. The first level set of names is called TDLs or Top Level Domains including gTDLs (generic) and ccTDLs (country code). Some examples of which are the prominent .com, .net and .org domains. Below these TDLs are the second and third level domain names which are typically open for end user reservations wishing to connect local area networks or LANs in the country.
They can also use an Australian domain name to run websites on the internet and create publicly accessible net resources. These domain names are sold by domain name registrars who administer these domains to the public. Individual internet host computers utilize domain names as hostnames. These are the leaf labels in DNS usually without further sub domain name space. They appear as a component in URLs or Uniform Resource Locators for internet resources like websites. These Australian domain names are also utilized as simple identification labels in order to indicate control or ownership of a resource like SIPs or Session Initiation Protocols.
