More information:

.us is the ccTLD for the United States of America. It is managed by Registry Services, LLC. Registry Services, LLC manages the .us domain name on behalf of the U.S. Department of Commerce (DOC).

History

.us was first established in 1985. Second level domains under .us did not become available for registration until April 2002.

Jon Postel was one of the original administrators for .us. who at that time also served as head of the Internet Assigned Numbers and Authority (IANA). Postel delegated the management of localities within the .us TLD hierarchy to individuals, organizations, and State governments. The operational guidelines drafted by the original administrators of the .us TLD states that the delegated managers are "trustees for the delegated domain and have a duty to serve the community. The designated [delegated] manager is the trustee of the domain for the domain itself and the global Internet community. Concerns about 'rights' and 'ownership' of domains are inappropriate. It is appropriate to be concerned about 'responsibilities" and 'service' to the community." The delegated managers worked voluntarily without pay as they perform registry or registration operations.

In 2001, the Department of Commerce, through the National Telecommunication and Information Administration (NTIA) awarded Neustar to serve as the administrator of the us TLD with the objective to further develop and expand the operation of the United States domain name. Neustar's contract was renewed on October 25, 2007. and then again in 2014 and 2019.

In 2020, Neustar was acquired by GoDaddy.

Locality-based Domains

Registrations in the locality space reflect the oldest part of the usTLD domain namespace. These registrations represent the political geography of the United States based on two-letter state abbreviations and divided further into localities, including cities, counties, parishes, townships, or local names (e .g., Alexandria.va.us). In addition to geographical locality names, the usTLD locality space also includes certain affinity names, for example, STATE, FED, K12, LIB, and NSN (Native Sovereign Nation). Locality and affinity names collectively compose the "locality space."

The administration of the usTLD Locality namespace is managed by entities and/or individuals called Delegated Managers who follow comprehensive technical and service requirements. Individually and as a group, Delegated Managers play a valuable role in the management of the usTLD Locality namespace. Delegated Managers work directly with the usTLD Administrator to maintain their usTLD Locatlity delegation(s). In order to ensure common and widespread best practices among Delegated Managers for the benefit of the Locality space users, the usTLD Delegated Manager Agreement sets forth the relative rights and responsibilities of Registry Services, as the usTLD Administrator, and each Delegated Manager. For existing Delegated Managers, an executed usTLD Delegated Manager agreement is required to continue delegation management services. The usTLD Administrator currently serves as Registry, Registrar, and Delegated Manager for all undelegated third-level locality domains (i.e. all third-level locality domains that do not have an assigned Delegated Manager) and their child domains (fourth/fifth/sixth level domains).
