IANA functions

The United States Departmentof Commerce's National Telecommunications and Information Administration (NTIA) remains committed to preserving a stable and secure Internet Domain Name System (DNS). Critical to the DNS is the continued performance of the Internet Assigned Numbers Authority (IANA) functions. The IANA functions have historically included: (1) The coordination of the assignment of technical Internet protocol parameters; (2) the administration of certain responsibilities associated with Internet DNS root zone management; (3) the allocation of Internet numbering resources; and (4) other services related to the management of the .ARPA and .INT top-level domains. The Internet Corporation for Assigned Names and Numbers (ICANN) performed the IANA functions, on behalf of the United States Government, through a contract with NTIA.
