Regional Internet Registries (RIR WHOIS) Ingrid A Regional Internet Registry (RIR) manages the allocation and registration of the number of internet resources within a particular region of the world. Registry Processing CIDR blocks are allocated and assigned by the Internet Corporation for Assigned Names and Numbers (ICANN) through its responsibility for the Internet Assigned Numbers Authority (IANA). Large CIDR ranges are allocated to regional registries. Each registry maintains a database of CIDR ranges allocated to themselves and those they’ve sub-allocated to Internet Service Providers (ISP) or Local Internet Registries (LIR) within their region. An ISP and local registry can further sub-allocate CIDR ranges or assign them to customers. Registrars can also directly assign CIDR ranges to customers.
