The Internet Corporation for Assigned Names and Numbers is a nonprofit organization responsible for coordinating the maintenance and procedures of several databases related to the namespaces and numerical spaces of the Internet, ensuring the network's stable and secure operation. ICANN performs the actual technical maintenance work of the Central Internet Address pools and DNS root zone registries pursuant to the Internet Assigned Numbers Authority (IANA) function contract. The contract regarding the IANA stewardship functions between ICANN and the National Telecommunications and Information Administration (NTIA) of the United States Department of Commerce ended on October 1, 2016, formally transitioning the functions to the global multistakeholder community.
A top-level domain (TLD) is one of the domains at the highest level in the hierarchical Domain Name System of the Internet. The top-level domain names are installed in the root zone of the name space. For all domains in lower levels, it is the last part of the domain name, that is, the last label of a fully qualified domain name. For example, in the domain name www.example.com, the top-level domain is com. Responsibility for management of most top-level domains is delegated to specific organizations by the Internet Corporation for Assigned Names and Numbers (ICANN), which operates the Internet Assigned Numbers Authority (IANA), and is in charge of maintaining the DNS root zone.
A domain name is an identification string that defines a realm of administrative autonomy, authority or control within the Internet. Domain names are used in various networking contexts and for application-specific naming and addressing purposes. In general, a domain name identifies a network domain, or it represents an Internet Protocol (IP) resource, such as a personal computer used to access the Internet, a server computer hosting a web site, or the web site itself or any other service communicated via the Internet. In 2017, 330.6 million domain names had been registered.
A domain name registry is a database of all domain names and the associated registrant information in the top level domains of the Domain Name System (DNS) of the Internet that enables third party entities to request administrative control of a domain name. Most registries operate on the top-level and second-level of the DNS.

The domain name org is a generic top-level domain (gTLD) of the Domain Name System (DNS) used in the Internet. The name is truncated from organization. It was one of the original domains established in 1985, and has been operated by the Public Interest Registry since 2003. The domain was originally intended for non-profit entities, but this restriction was not enforced and has been removed. The domain is commonly used by schools, open-source projects, and communities, but also by some for-profit entities. The number of registered domains in org has increased from fewer than one million in the 1990s, to ten million as of June 2013.

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 initial set of 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.
A GeoTLD is a top-level domain in the Domain Name System of the Internet using the name of or invoking an association with a geographical, geopolitical, ethnic, linguistic or cultural community.
