What is a Domain Name?
A domain name is an addressing construct used for identifying and locating computers on the Internet. Domain names provide a system of easy-to-remember Internet addresses, which can be translated by the Domain Name System (DNS) into the numeric addresses (Internet Protocol (IP) numbers) used by the network. A domain name is hierarchical and often conveys information about the type of entity using the domain name.
A domain name is simply a label that represents a domain, which is a subset of the total domain name space. Domain names at the same level of the hierarchy must be unique. Thus, for example, there can only be one .com.au at the top-level of the hierarchy, and only one ausregistry.com.au at the next level of the hierarchy.
