1.  Introduction

   The Internet Engineering Task Force (IETF) and its predecessors have
   traditionally separated the publication of protocol specifications in
   immutable Request for Comments (RFCs) and the registries containing
   protocol parameters.  The latter is  Traditionally, the registries are maintained by
   a set of functions
   traditionally known collectively as the Internet Assigned
   Numbers Authority (IANA).  Dating back to the earliest days of the
   Internet, specification publication and the registry operations were
   tightly coupled: Jon Postel of the Information Sciences Institute
   (ISI) of the University of Southern California (USC) was responsible
   for both RFC publication and IANA registry operation.  This tight
   coupling had advantages, but it was never a requirement.  Indeed,
   today the RFC Editor and IANA registry operation are provided by
   different entities.

   Internet registries are critical to the operation of the Internet,
   since
   because they provide a definitive record of the value and meaning of
   identifiers that protocols use when communicating with each other.
   Almost every Internet protocol makes use of registries in some form.
   At the time of writing, the IANA maintains more than two thousand
   protocol parameter registries.

   Internet registries hold protocol identifiers consisting of constants
   and other well-known values used by Internet protocols.  These values
   can be numbers, strings, addresses, and so on.  They are uniquely
   assigned for one particular purpose or use.  Identifiers can be
   maintained in a central list (such as a list of cryptographic
   algorithms) or they can be hierarchically allocated and assigned by
   separate entities at different points in the hierarchy (such as IP
   addresses and domain names).  To maximize trust and usefulness, usefulness of the
   IANA registries, the principles in this document should be taken into
   consideration for centralized registries as well as hierarchically
   delegated registries.  In hierarchically delegated registries,
   entries nearest to top-level top level have broad scope, but lower-level
   entries have narrow scope.   The IAB Internet Architecture Board (IAB)
   will encourage support for these principles in all delegations of
   Internet identifiers.

   The registry system is built on trust and mutual cooperation.  The
   use of the registries is voluntary and is not enforced by mandates or
   certification policies.  While the use of registries is voluntary, it
   is noted that the success of the Internet creates enormous pressure
   to use Internet protocols and the identifier registries associated
   with them.

   This document provides principles for the operation of IANA
   registries, ensuring that protocol identifiers have consistent
   meanings and interpretations across all implementations and
   deployments, and thus providing the necessary trust in the IANA
   registries.

2.  Principles for the Operation of IANA Registries

   The following key principles underscore the successful functioning of
   the IANA registries, and they provide a foundation for trust in those
   registries:

   Ensure Uniqueness:  The same protocol identifier must not be used for
      more than one purpose.

   Stable:  Protocol identifier assignment must be lasting.

   Predictable:  The process for making assignments must not include
      unexpected steps.

   Public:  The protocol identifiers must be made available in well-
      known locations in a manner that makes them freely available to everyone in well-known
      locations.
      everyone.

   Open:  The process that sets the policy for protocol identifier
      assignment and registration must be open to all interested
      parties.

   Transparent:  The protocol registries and their associated policies
      should be developed in a transparent manner.

   Accountable:  Registry policy development and registry operations
      need to be accountable to the affected community.

3.  Discussion

   The principles discussed in Section 2 provide trust and confidence in
   the IANA registries.  This section expands on these principles.

3.1.  Ensuring Uniqueness, Stability, and Predictability

   Protocol identifier assignment and registration must be unique,
   stable, and predictable.  Developers, vendors, customers, and users
   depend on the registries for unique protocol identifiers that are
   assigned in a stable and predictable manner.

   A protocol identifier may only be reassigned for a different purpose
   after due consideration of the impact of such a reassignment, and if
   possible, with the consent of the original assignee.

   Recognizing that some assignments involve judgment, such as those
   involving a designated expert [RFC5226], a predictable process does
   not require completion in a predetermined number of days.  Rather, it
   means that no unexpected steps are introduced in the process of
   making an assignment.

3.2.  Public

   Once assigned, the protocol identifiers must be made available in a
   manner that makes them freely available to everyone without
   restrictions.  The use of a consistent publication location builds
   confidence in the registry.  This does not mean that the publication
   location can never change, but it does mean that it must change
   infrequently and only after adequate prior notice.

3.3.  Open and Transparent

   The process that sets the policy for protocol identifier assignment
   and registration must be open to all interested parties and operate
   in a transparent manner.

   When a registry is established, a policy is set for the addition of
   new entries and the updating of existing entries.  While making
   additions and modifications, the registry operator may expose
   instances where policies lack of clarity.  When this occurs, the
   registry operator should provide helpful feedback to allow those
   policies to be improved.  In addition, the registry operator not
   being involved in establishing registry policy avoids the risks
   associated with (perceptions of) favoritism and unfairness.

   Recognizing that some assignments involve judgment, such as those
   involving a designated expert [RFC5226], the recommendations by
   designated experts must be visible to the public to the maximum
   extent possible and subject to challenge or appeal.

3.4.  Accountable

   The process that sets the policy for IANA registries and the
   operation of the registries must be accountable to the parties that
   rely on the protocol identifiers.  Oversight is needed to ensure
   these are properly serving the affected community.

   In practice practice, accountability mechanisms for the registry operator may
   be defined by contract, memoranda of understanding, or service level
   agreements (SLAs).  An oversight body uses these mechanisms to ensure
   that the registry operator is meeting the needs of the affected
   community, but the
   community.  The oversight body is held accountable to the affected
   community by vastly different mechanisms, for instance recall and
   appeal processes.

   For protocol parameters [RFC6220], the general oversight over of the IANA
   function is performed by the IAB as a chartered responsibility from
   [RFC2850].  In addition addition, the IETF Administrative Oversight Committee
   (IAOC), a body responsible for IETF administrative and financial
   matters [BCP101], maintains an SLA with the current registry
   operator, the Internet Corporation for Assigned names and Numbers
   (ICANN), thereby specifying the operational requirements with respect
   to the coordination, maintenance, and publication of the protocol
   parameter registries.  Both the IAB and the IAOC are accountable to
   the larger Internet community and are being held accountable through
   the IETF Nomcom process [BCP10].

   For the Internet Number Registries [RFC7249], oversight is performed
   by the Regional Internet Registries (RIRs) as described RFC 7020
   [RFC7020].  The RIRs are member-based organizations, and they are
   accountable to the affected community by elected governance boards.
   Furthermore, per agreement between the RIRs and ICANN, the policy
   development for the global IANA number registries is coordinated by a
   community-elected number council and subject to process review before
   ratification by the ICANN Board of Trustees [ASOMOU].

4.  Security Considerations

   Internet Registries are critical to elements of Internet security.
   The principles described in this document are necessary for the
   Internet community to place trust in the IANA registries.
