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.
IP Address: 184.108.40.206 maps to the ausregistry.com.au domain name.
A domain name is hierarchical and often conveys information about the type of entity that has registered the domain name.
ausregistry.com.au is a Third-Level Domain (3LD), Australian country code domain name.
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.
Domain names must:
be at least 2 characters long;
contain only letters (a-z), numbers (0-9) and hyphens (-), or a combination of these;
start and end with a number or a letter, not a hyphen; and
not contain hyphens in the third and fourth position (eg. ab–cd.com.au).
