The IU Knowledge Base further explains that a domain is included in each website address, network address and email address. For example, the site says that the domain in the Web address www.indiana.edu/people/address.shtml is "indiana." The directory in the domain is "people," and the file in directory is ".shtml." A domain is obtained by choosing and buying one from a domain registrar.

Domains on the Internet are categorized by levels. Top-level domains or TLDs include .com, .net, .edu and .org. CcTLDs represent top-level domains of countries, while gTLDs are generic top-level domains. Domain names are governed by the Internet Corporation for Assigned Names and Numbers, which oversees the creation of TLDs as well as their distribution.

Domain name servers maintain a connection between domain names and IP addresses. The DNS system is used by computers to transmit information online.
