Internet Resource Allocation
Internet number resources are distributed in a hierarchical manner. The Internet Assigned Numbers Authority (IANA) delegates large ranges of Internet number resources to the RIRs, which then allocate the resources within their regions to members, Local Internet Registries, National Internet Registries, and end-users. A list of term definitions is available at the Internet Registry System page.
