IANA LogoLearn more about the NTIA's plans to transition out of IANA stewardship

The Internet Assigned Numbers Authority (IANA) is responsible for the global coordination of the DNS Root, IP addressing, and other Internet protocol resources. It is a set of functions that is currently contracted out by the National Telecommunications and Information Administration (NTIA), an agency in the U.S. Department of Commerce. The IANA function is currently carried out by ICANN.

With regard to Internet number resources, IANA's role is to allocate IP addresses and AS Numbers from the pools of unallocated resources to the Regional Internet Registries (RIRs) according to their needs, and to document protocol assignments made by the IETF. When an RIR requires more IP addresses for allocation or assignment within its region, IANA makes an additional allocation to the RIR.

IANA does not make allocations directly to ISPs or end users except in specific circumstances, such as allocations of multicast addresses or other protocol-specific needs.

Global Policy Development

The policies under which the IANA role is carried out are referred to as Global Addressing Policies, and must be agreed to by all of the five RIR communities. Any new policy proposal must go through the Policy Development Process in each RIR and be ratified by each community, and this process will then be reviewed by the ASO Address Council (ASO AC) before the new global policy is adopted.

Legacy IPv4 Address Space Returned to IANA

On 22 April 2014, the RIPE NCC handed over 5,376 returned legacy IPv4 addresses to IANA. This is the second time the RIPE NCC has returned legacy IPv4 addresses to IANA. For more information, please see the original news item and related documents.

Update on the IANA Transition

The RIPE NCC has published a section on its website that provides background information on the IANA functions, the role of stewardship of IANA and the RIPE NCC’s relationship to IANA.

IANA Stewardship Transition
The RIPE Community and the Evolution of the IANA Functions

On Friday 14 March, the United States Government announced that it intends to transition stewardship of key Internet functions (including the Internet Assigned Numbers Authority, or IANA) to the global multi-stakeholder community. It has asked ICANN to facilitate, in consultation with the global multi-stakeholder community, the development of a proposal for the transition.

NRO Letter to ICANN: The Future of the IANA Contract
Free Pool of IPv4 Address Space Depleted

The Number Resource Organization (NRO) announced today that the free pool of available IPv4 addresses is now fully depleted. On Monday, January 31, the Internet Assigned Numbers Authority (IANA) allocated two blocks of IPv4 address space to APNIC, the Regional Internet Registry (RIR) for the Asia Pacific region, which triggered a global policy to allocate the remaining IANA pool equally between the five RIRs. Today IANA allocated those blocks. This means that there are no longer any IPv4 addresses available for allocation from the IANA to the five RIRs.
