A top-level domain is the part of the domain name located to the right of the dot ("."). The most common TLDs are .com, .net and .org. Several new top-level domains have been added to the menu including, .biz, .info, .name, and .ws. The top-level domains have certain guidelines attached, but are for the most part available to any registrant, anywhere in the world. Exceptions are the restricted TLDs (rTLDs) which include .aero, .biz, .edu, .mil, .museum, .name, and .pro that require the registrant to represent a certain type of entity, or to belong to a certain community. The .name TLD is available strictly for individuals, while .edu is reserved for educational entities, such as universities or high schools. Where appropriate, a top-level domain name can be of geographic significance. These are called country-code TLDs (ccTLDs) and include such top-level domains as .cn (China), .de (Germany), .fm (Micronesia), .jp (Japan), .sg (Singapore), .tv (Tuvalu), .uk (United Kingdom), and .us (United States).
