The Internet community is actively discussing the Internet Assigned Numbers Authority (IANA) stewardship transition process.  As part of the numbers community, ARIN encourages you to get involved.

On 14 March 2014 the US government announced a plan transition oversight of the Internet Assigned Numbers Authority (IANA) functions contract from the National Telecommunications and Information Administration (NTIA) to the global multistakeholder community.  The current contract expires on 30 September 2015.  Historically managed by the Internet Corporation for Assigned Names and Numbers (ICANN), IANA functions are part of Internet infrastructure and include responsibility for allocating and maintaining the unique codes and numbering systems used in Internet technical standards.

The IANA Functions

The IANA functions consist of the following responsibilities:

  • Coordination of the assignment of technical Internet protocol parameters through the Internet Engineering Task Force (IETF)
  • Administration of and coordination of Internet domain name system (DNS) root zone management
  • Allocation of Internet number resources to the Regional Internet Registries (RIRs)
  • Management of the .ARPA and .INT top-level domains (TLDs)

This ICANN infographic details the three core areas of the IANA functions – Number Resources, Protocol Parameters, and Domain Names.

Principles for the Transition Proposal

The NTIA has communicated to ICANN that the transition proposal must have broad community support and address the following four principles:

  • Support and enhance the multistakeholder model;
  • Maintain the security, stability, and resiliency of the Internet DNS;
  • Meet the needs and expectation of the global customers and partners of the IANA services; and,
  • Maintain the openness of the Internet.

 The ARIN and NRO Process

The ARIN community is discussing the IANA Stewardship Transition planning process via an open public mailing list to develop a proposal to submit to the Number Resource Organization (NRO).  Each RIR is likewise independently holding regional consultations to bring to the NRO. The next step will be to further consolidate ARIN input with the input of the other four Regional Internet Registries in early 2015 with the goal of coming to a complete submission on behalf of the Number Resource Organization (NRO) to the ICG.

The ICANN Process

ICANN is responsible for spearheading the development of a proposal by the global multistakeholder community for the transition of the current role played by NTIA in the coordination of the Internet’s domain name system (DNS) along with other key stakeholders. Visit the ICANN NTIA IANA functions’ stewardship transition microsite

Based on community discussions, ICANN established an IANA Stewardship Transition Coordination Group (ICG) to facilitate the transition process.  It consists of 27 individuals representing different 13 communities including the ALAC, ASO, ccNSO, GAC, GNSO, gTLD Registries, ICC/BASIS, IAB, IETF, ISOC, NRO, RSSAC, and SSAC.
