Regional internet registry

(also RIR)

Regional internet registry definition

A regional internet registry is an organization that performs a crucial role in managing and distributing internet resources, such as IP addresses and AS numbers, within a specific geographic region.

Regional internet registries act as intermediaries between internet service providers (ISPs), enterprises, and organizations that need IP addresses for their networks. They ensure a fair and efficient allocation of these resources while following global Internet standards and policies.

Each regional internet registry operates independently on a regional basis, where each region typically has its designated regional internet registry. They cooperate globally, whereas the Internet Assigned Numbers Authority (IANA) delegates the allocation of IP addresses to the RIRs.
