IANA Stewardship Transition Completed

Posted: Monday, 03 October 2016

On 1 October 2016 the contract between the Internet Corporation for Assigned Names and Numbers (ICANN) and the United States Department of Commerce National Telecommunications and Information Administration (NTIA), to perform the Internet Assigned Numbers Authority (IANA) functions, officially expired.


The expiration of this contract established the commencement date of the Service Level Agreement (SLA) entered into between ICANN and the five Regional Internet Registries (RIRs) for the administration of the IANA Numbering Services, signed on 29 June 2016.

The realization of the IANA stewardship transition is an important milestone in Internet coordination activities, and all members of the global multistakeholder community should be proud of their efforts in making this happen.

To provide ongoing oversight and accountability for the IANA Numbering Services administrator, the Internet Number Community proposal to the IANA Stewardship Coordination Group (ICG) called for the establishment of an IANA Numbering Services Review Committee, whose role is to ensure the Service Level Agreement (SLA) for the IANA Numbering Services is met by the IANA Numbering Services Operator. The committee was required as part of the Internet Number Community's proposal to replace US Government oversight of the IANA functions.

The review committee charter is available for review at: https://www.nro.net/wp-content/uploads/Review-Committee-Charter_FINALclean.pdf

Three representatives from each Regional Internet Registry (RIR) community will serve on the committee. For ARIN, these roles will be filled by the two community-elected NRO Number Council members and one ARIN staff member who is appointed by the ARIN Board of Trustees will participate on the ARIN community's behalf.

ARIN is pleased to announce the seating of its representatives to the IANA Numbering Services Review Committee:

  • Louie Lee- NRO NC
  • Jason Schiller – NRO NC
  • Nate Davis – ARIN staff representative
