Introduction The administrative structures of the Internet Numbers Registry System described in this document are largely the result of the interaction of operational practices, existing routing technology, number resource assignments that have occurred over time, and network architectural history. Further discussion and analysis of these interactions are outside the scope of this document. This document provides information about the current Internet Numbers Registry System used in the distribution of globally unique Internet Protocol (IP) address space and autonomous system (AS) numbers. It also describes the processes used for further evolution of the Internet Numbers Registry System. This document does not propose any changes to the current operation of this system. This document replaces RFC 2050. Since the publication of RFC 2050, the Internet Numbers Registry System has changed significantly. This document describes the present Internet Numbers Registry System. Housley, et al. Expires January 01, 2014 [Page 2] Internet-Draft Internet Registry System June 2013 2. Goals Internet number resources are currently distributed according to the following (non-exclusive) goals: 1) Allocation Pool Management: Due to the fixed lengths of IP addresses and AS numbers, the pools from which these resources are allocated are finite. As such, allocations must be made in accordance with the operational needs of those running the networks that make use of these number resources and by taking into consideration pool limitations at the time of allocation. 2) Hierarchical Allocation: Given current routing technology, the distribution of IP addresses in a hierarchical manner increases the likelihood of continued scaling of the Internet's routing system. As such, it is currently a goal to allocate IP addresses in such a way that permits aggregation of these addresses into a minimum number of routing announcements. However, whether IP addresses are actually announced to the Internet, and the manner of their advertisement into the Internet's routing system is an operational consideration outside of the scope of the Internet Numbers Registry System. 3) Registration Accuracy: A core requirement of the Internet Numbers Registry System is to maintain a registry of allocations to ensure uniqueness and to provide accurate registration information of those allocations in order to meet a variety of operational requirements. Uniqueness ensures that IP addresses and AS numbers are not allocated to more than one party at the same time. These goals may sometimes conflict with each other or be in conflict with the interests of individual end-users, Internet service providers, or other number resource consumers. Careful analysis, judgment, and cooperation among registry system providers and consumers at all levels via community-developed policies is necessary to find appropriate compromises to facilitate Internet operations. 3. Internet Numbers Registry System Structure The Internet Registry (IR) hierarchy was established to provide for the allocation of IP addresses and AS numbers with consideration to the above goals. This hierarchy is rooted in the Internet Assigned Numbers Authority (IANA) address allocation function, which serves a set of "Regional Internet Registries" (RIRs); the RIRs then serve a set of "Local Internet Registries" (LIRs) and other customers. LIRs in turn serve their respective number resource consumers (which may be themselves, their customers, "sub-LIRs", etc.) Housley, et al. Expires January 01, 2014 [Page 3] Internet-Draft Internet Registry System June 2013 IETF The IETF specifies the underlying technical facilities and constraints of Internet numbers administered by the Internet Numbers Registry System. These specifications are aimed at enabling and protecting the long-term viability of the Internet and adjustments to those specifications are made over time as circumstances warrant. The IETF has also reserved portions of the Internet number spaces and identifiers for future needs. IANA The Internet Assigned Numbers Authority (IANA) is a role, not an organization. For the Internet Numbers Registry System, the IANA role manages the top of the IP address and AS number allocation hierarchies. The Internet Corporation for Assigned Names and Numbers (ICANN) currently fulfills the IANA role in accordance with the IETF-ICANN "Memorandum of Understanding Concerning Technical Work of the Internet Assigned Numbers Authority", which was signed and ratified in March 2000 [RFC2860]. In addition, ICANN performs the IANA services related to the IP address space and AS numbers according to global number resource policies that have been developed by the community and formalized under a Memorandum of Understanding between ICANN and the Regional Internet Registries [ASOMOU] and documented in [ICANNv4], [ICANNv6], and [ICANNASN]. Regional IRs In order to promote distribution of the Internet number resource registration function, RFC 1366 proposed delegating responsibility to regional bodies. These bodies became known as the Regional Internet Registries (RIRs). The RIRs operate in continent-sized geopolitical regions. Currently there are five RIRs: AfriNIC serving Africa, APNIC serving parts of Asia and the Pacific region, ARIN serving North America and parts of the Caribbean, LACNIC serving Latin America and parts of the Caribbean, and RIPE NCC serving Europe, parts of Asia and the Middle East. The RIRs were established in a bottom-up fashion via a global policy process that has been documented as the ICANN "Internet Consensus Policy 2" [ICP-2], which details the principles and criteria for establishment of Regional Internet Registries. The RIRs also conduct regional number policy development used in the administration of their number resources for which they are responsible. Housley, et al. Expires January 01, 2014 [Page 4] Internet-Draft Internet Registry System June 2013 Local IRs Local Internet Registries (LIRs) are established through a relationship with the body from which they received their addresses, typically the RIR that serves the region in which they operate, a parent LIR, or other numbers allocating entity. In cases where LIRs span multiple regions those LIRs have established relationships with multiple RIRs. LIRs perform IP address allocation services for their Customers, typically ISPs, end users, or "child" or "sub-" LIRs. 4. Internet Numbers Registry Technical Considerations As a result of the system of technical standards and guidelines established by the IETF as well as historical and operational constraints, there have been technical considerations regarding the services provided by the Internet Numbers Registry System as it evolved. These technical considerations have included: 1) Reverse DNS: In situations where reverse DNS was used, the policies and practices of the Internet Numbers Registry System have included consideration of the technical and operational requirements posed by reverse DNS zone delegation [RFC5855]. 2) Public WHOIS: The policies and practices of the Internet Numbers Registry System have included consideration of the technical and operational requirements for supporting WHOIS services [RFC3013][RFC3912]. As the Internet and the Internet Numbers Registry System continue to evolve, it may be necessary for the Internet community to examine these and related technical and operational considerations and how best to meet them. This evolution is discussed in the next section. 5. Internet Numbers Registry Evolution Over the years, the Internet Numbers Registry System has developed mechanisms by which the structures, policies, and processes of the Internet Numbers Registry System itself can evolve to meet the changing demands of the global Internet community. Further evolution of the Internet Numbers Registry System is expected to occur in an open, transparent, and broad multi-stakeholder manner. Per the delineation of responsibility for Internet address policy issues specified in the IETF/IAB/ICANN MOU [RFC2860], discussions regarding the evolution of the Internet Numbers Registry System structure, policy, and processes are to take place within the ICANN framework and will respect ICANN's core values [ICANNBL]. These core Housley, et al. Expires January 01, 2014 [Page 5] Internet-Draft Internet Registry System June 2013 values encourage broad, informed participation reflecting the functional, geographic, and cultural diversity of the Internet at all levels of policy development and decision-making, as well as the delegation of coordination functions and recognition of the policy roles of other responsible entities that reflect the interests of affected parties. The discussions regarding Internet Numbers Registry evolution must also continue to consider the overall Internet address architecture and technical goals referenced in this document. The foregoing does not alter the IETF's continued responsibility for the non-policy aspects of Internet addressing such as the architectural definition of IP address and AS number spaces and specification of associated technical goals and constraints in their application, assignment of specialized address blocks, and experimental technical assignments as documented in RFC 2860. In addition, in the cases where the IETF sets technical recommendations for protocols, practices, or services which are directly related to IP address space or AS numbers, such recommendations must be taken into consideration in Internet Numbers Registry System policy discussions regardless of venue. 6. Summary of Changes Since RFC 2050 Since RFC 2050 was published, the Internet and the Internet Numbers Registry System have undergone significant change. This document describes the Internet Numbers Registry System as it presently exists and omits policy and operational procedures that have been superseded by ICANN and RIR policy since RFC 2050 publication. One particular change of note, RFC 2050 defined an appeal process and included: If necessary, after exhausting all other avenues, the appeal may be forwarded to IANA for a final decision. Each registry must, as part of their policy, document and specify how to appeal a registry assignment decision. The RIRs have developed consensus-based policies for appeals, and over time, they have become accepted by the respective RIR communities. As a result, the ability to further appeal to IANA is no longer appropriate. Housley, et al. Expires January 01, 2014 [Page 6] Internet-Draft Internet Registry System June 2013 7. Security Considerations It is generally recognized that accuracy and public availability of Internet registry data is often an essential component in researching and resolving security and operational issues on the Internet. 8. IANA Considerations No updates to the registries are suggested by this document. [RFC Editor: Please remove this section prior to publication.] 9.
