The Domain Name System of the Internet consists of a set of top-level domains which constitute the root domain of the hierarchical name space and database. In the growth of the Internet, it became desirable to expand the set of initially six generic top-level domains in 1984. As a result new top-level domain names have been proposed for implementation by ICANN. Such proposals included a variety of models ranging from adoption of policies for unrestricted gTLDs that could be registered by anyone for any purpose, to chartered gTLDs for specialized uses by specialized organizations. In October 2000, ICANN published a list of proposals for top-level domain strings it had received.
