Aregional Internet registry (RIR) is an organization that manages the allocation and registration ofInternet number resources within a region of the world. Internet number resources includeIP addresses andautonomous system (AS) numbers.
The regional Internet registry system evolved, eventually dividing the responsibility for management to a registry for each of five regions of the world. The regional Internet registries are informally liaised through the unincorporatedNumber Resource Organization (NRO), which is a coordinating body to act on matters of global importance.[1]
As of 2005, there are currently five regional registries:
Regional Internet registries are components of the Internet Number Registry System, which is described inIETF RFC 7020,[7] where IETF stands for the Internet Engineering Task Force. TheInternet Assigned Numbers Authority (IANA) delegates Internet resources to the RIRs who, in turn, follow their regional policies to delegate resources to their customers, which includeInternet service providers and end-user organizations.[8] Collectively, the RIRs participate in theNumber Resource Organization (NRO),[9] formed as a body to represent their collective interests, undertake joint activities, and coordinate their activities globally. The NRO has entered into an agreement withICANN for the establishment of theAddress Supporting Organisation (ASO),[10] which undertakes coordination of global IP addressing policies within the ICANN framework.
TheNumber Resource Organization (NRO) is an unincorporated organization uniting the five RIRs.[9] It came into existence on October 24, 2003, when the four existing RIRs entered into amemorandum of understanding (MoU) in order to undertake joint activities, including joint technical projects and policy coordination. The youngest RIR,AFRINIC, joined in April 2005.
The NRO's main objectives are to:
Alocal Internet registry (LIR) is an organization that has been allocated a block ofIP addresses by a RIR, and that assigns most parts of this block to its own customers.[11] Most LIRs areInternet service providers, enterprises, or academic institutions. Membership in a regional Internet registry is required to become a LIR.
