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.

Promoting Internet Growth and Innovation Through Multistakeholder Internet Governance

March 19, 2014

This past Friday, NTIA asked the Internet Corporation for Assigned Names and Numbers (ICANN) to convene global stakeholders to develop a proposal to transition the U.S. government’s stewardship of the Internet’s Domain Name System (DNS). This marks a major milestone toward the final phase of the privatization of the DNS, which was first outlined by the U.S. Government in 1997.

We believe the timing is right for this transition, and a broad group of stakeholders – both domestically and internationally – have expressed their support and cooperation in this process.

Cisco commended NTIA for outlining a “powerful process for the move towards full privatization and globalization of DNS management.” Microsoft said it “relies on the stability, resilience and security of the DNS system to enable our cloud services – and we are confident that now is the right time to complete this transition.”  Other industry giants like AT&T, Verizon, and Google, similarly issued statements in support of our announcement.
