1. 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.

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, Internet and the manner
of their advertisement into the Internet's routing system is an are
operational consideration considerations 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, 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 are 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.)
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 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. (Note: RFC 1366 was replaced by RFC 1466,
which was replaced by RFC 2050.) These bodies became known as the
Regional Internet Registries (RIRs). The RIRs operate in
continent-sized geopolitical regions. Currently 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 the number resources for
which they are responsible.

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 number-allocating entity. In
cases where LIRs span multiple regions regions, those LIRs have
established relationships with multiple RIRs. LIRs perform IP
address allocation services for their Customers, customers, typically ISPs,
end users, or "child" or "sub-" LIRs. child LIRs (also known as "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]. [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
values encourage broad, informed participation reflecting the
functional, geographic, and cultural diversity of the Internet at all
levels of policy development and decision-making, 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 that 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 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 the publication of RFC 2050 publication. 2050.

One particular change of note, note is that 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.

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.
