Abstract
RFC 7020 describes the Internet Numbers Registry System, explaining how IANA and the five Regional Internet Registries (ARIN, RIPE NCC, APNIC, LACNIC, AFRINIC) coordinate the global allocation of IPv4, IPv6, and AS number resources. It outlines the policies, procedures, and relationships that govern number resource management across the hierarchy.
Why This RFC Matters
The Internet Numbers Registry System is the governance backbone for IP address allocation. RFC 7020 provides the authoritative description of how IANA, RIRs, and LIRs interact to allocate address space in a coordinated, policy-driven manner. Understanding this system is essential for network operators seeking address allocations, for RPKI certificate issuance, and for participation in Internet governance discussions about address policy.
