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.

Reviewing the IANA Transition Proposal

March 11, 2016

Over the past two decades, the Internet has touched the lives of billions of people around the globe in profound ways.  It has fueled economic growth, giving even the most remote villages the opportunity to sell their products in faraway lands.  It has fueled innovation, connecting mobile gadgets and household appliances.  And it has torn down barriers to speech, enabling diverse viewpoints to be heard across the political spectrum.

The Obama Administration is committed to doing everything within our power to preserve and protect the open, free-flowing global Internet, which has revolutionized the world.  That’s why two years ago, we announced our intention to transition the U.S. government’s stewardship role of the Internet Domain Name System to the global multistakeholder community.

Since our announcement, the Internet community – made up of businesses, technical experts, academics and civil society – has risen to the challenge by developing a transition plan that has achieved broad community support.  The community delivered that proposal to NTIA yesterday, marking the culmination of the largest multistakeholder process ever undertaken.  Stakeholders spent more than 26,000 working hours on the proposal, exchanged more than 33,000 messages on mailing lists, and held more than 600 meetings and calls.
