1. Introduction
1.1. Internet Registries and Interoperability on the Internet
Internet registries are critical to the operation of the Internet,
since 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 Internet Assigned Numbers Authority
(IANA) maintains over one thousand protocol parameter registries.
Management of Internet registries must be predictable, stable and
secure, in order to ensure that protocol identifiers have consistent
meanings and interpretations across all implementations and
deployments. For example, TCP port number 80 is globally understood
to denote the "http" service.
Internet registries hold identifiers consisting of constants and
other well-known values used by Internet protocols. These values can
be numbers, strings, addresses, etc. They are uniquely assigned for
one particular purpose or use. Identifiers can be maintained in
within a central list (e.g. a list of cryptographic algorithms for
use in a particular protocol) or they can be hierarchically allocated
and assigned by separate entities at different points in the
hierarchy (such as for IP addresses and domain names).
Stable and predictable assignment and registration of protocol
identifiers for Internet protocols is of great importance to many
stakeholders, including developers, vendors, and customers, as well
as users of devices, software, and services on the Internet. These
stakeholders use and depend on registries and implicitly trust the
registry system to be stable and predictable. 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 (e.g. as an enabler of social and economic
IAB & Kolkman Expires September 20, 2014 [Page 3]
Internet-Draft IANA framework March 2014
development) does create enormous pressure to utilize Internet
protocols, and hence the protocol registries and their associated
policies should be developed in a transparent manner which is open to
all interested parties.
Stability and consistency of Internet registries is achieved through
the definition of appropriate and clear policies for making additions
to or updating existing entries. Such policies must take into
account the technical and operational properties of the technology
that makes use of the registries. At the same time, it must be
possible to evolve the systems and policies for managing registry
contents as the Internet itself evolves. This description of
responsibilities, entities, and functions within the scope of IANA
serves as an aid for a structured approach to the potential evolution
of the Internet Registries model.
1.2. The IANA function and Internet Registries
The Internet Engineering Task Force (IETF) and its predecessors have
traditionally separated the publication mechanism of its protocol
specifications, published in immutable Request for Comments (RFCs),
from the registries containing protocol parameters. The latter is
maintained by a set of functions traditionally known collectively as
the Internet Assigned Numbers Authority (IANA). Dating back to the
somewhat before the earliest days of the Internet, the specification
publication function and the registry maintenance functions were
tightly coupled: Jon Postel of the Information Sciences Institute
(ISI) of the University of Southern California (USC) was responsible
for both the RFC publications and the IANA function. However, this
tight coupling was never a requirement. Indeed, today the RFC Editor
and IANA function are contracted to different entities. (The RFC
publication process and the IANA protocol parameter policy
development process and oversight remain closely coupled. For
example, the Internet Architecture Board (IAB) has oversight
responsibilities over the both RFC Series and IANA [RFC2850].)
One way to approach Internet Registry Management is to examine the
what, why, who and how. Internet Registries are tables with
assignments and allocations of values (the 'what'), established by
explicit directions contained within RFC documents (the 'why'). The
framework described in this document applies to individual
registries. These registries are colloquially grouped into 3
classes: Names, Numbers, and IETF Protocol Parameters. The framework
applies, with some nuance, to all registries, regardless of their
class. Within the context of this document the term "Internet
registries" is used for those the registries that are currently
organized as Domain Names, Number Resources, and IETF Protocol
Parameter registries.
IAB & Kolkman Expires September 20, 2014 [Page 4]
Internet-Draft IANA framework March 2014
One of the nuances that come into play is that some protocol
parameters within these classes are "general use", and registry
values assigned upon request to specific parties in accordance with
the registry policy. Such assignments are generally unique in
nature, i.e. only one party is associated with each general- purpose
registry entry. Coordination (or automation) is necessary to provide
uniqueness of assignments in each registry, but it is particularly
important in the general purpose registries given the large number of
assignments involved. Several of the general purpose registries
(DNS, IPv4, IPv6, ASNs) have been delegated to parties which are
believed to be reasonably representative of the communities dependent
upon those registries (e.g. ccTLD, and Regional Internet Registries).
In this framework we identify major four roles: The Policy, The
Oversight, the Evaluation Coordination, and Maintenance/Publication
Roles (the latter two are both both implementation aspects). The
entities that perform each of these roles can be interpreted as 'the
who' while the ways in which they carry out their roles determine
'the how'.
Within the IETF, the term "IANA" is often used to describe functions
belonging to the Evaluation Coordination and Maintenance/Publication
roles (as described below). In this document we use the term IANA or
IANA function(s) independent of the entities that implement those
functions (the 'who'). Currently, according to the Memorandum of
Understanding[RFC2860], the maintenance, implementation and
publication of most of the IETF protocol parameter registries are
performed by the Internet Corporation for Assigned Names and Numbers
(ICANN).
1.3. Framework for Internet Registries
This document provides a framework for describing the management of
Internet Registries as they are currently implemented. In Section 2
it defines terminology describing the various roles and
responsibilities associated with those roles. In Section 3 we
enumerate a few key principles for the implementation of the
framework. In Section 4 we discuss the existing context for these
principles and other features of the framework. Finally, in
Section 5 we provide a number of examples on how the framework
applies today. The examples demonstrate how the framework is applied
to the situation today and its utility going forward.
This document may be read independent of [RFC6220] and [RFC7020].
Those documents identify the specific requirements for the IETF
Protocol Parameter registries and the Internet Numbers Registry
System. As such, they provide context and examples for some of the
subject matter of this document. Those requirements apply only to
IAB & Kolkman Expires September 20, 2014 [Page 5]
Internet-Draft IANA framework March 2014
those subsets of the current collection of IANA function Internet
registries.
The authors are aware that this framework uses fewer, slightly
different, and more generic terms to describe the various roles than
[RFC6220]. [RFC6220] is a document that specifically pertains to the
IETF protocol parameter registries.
For instance, [RFC6220] section 2.1 "Protocol Parameter Registry
Operator Role" describes the full set of responsibilities for the
operator(s) of the IETF Protocol Parameter registries. These
responsibilities map to the Implementor aspects in Section 2.2 and
Section 2.3 below. [RFC6220] also describes the role of the IETF
Administrative Oversight Committee (IAOC) and IETF Trust. These
bodies have specific responsibilities in the wider IETF and are
responsible for contracting and IPR respectively. Within this
framework they should be considered part of the 'oversight role'.
The words must, should, shall, required, may and such should not be
interpreted as normative language as defined in [RFC2119], but in
their plain English meaning.
2. Roles in Relation to Internet Registries
In this section we discuss the roles relevant to Internet Registries
in terms of an abstract registry that is defined as part of an
arbitrary technical specification.
Registry management involves 4 roles. First, a policy development
role that defines the purpose of the registry and the process and
requirements for making additions or updates. Second, roles that
refer to the operational process for processing change requests to a
registry and for publishing its contents, both implementation
aspects. Finally, an oversight role that refers to a high-level
responsibility for ensuring that the other two roles are operating
satisfactorily and stepping in if significant changes are needed in
the policies or implementation of a registry. Each of these roles is
described in more detail in the following subsections.
2.1. The Policy Role
Description:
Registries may need to have additional values added, or an existing
entry may need to be removed, clarified, or updated in some manner.
The Policy Role creates the registry and defines the policies that
describes who can make updates or additions, what sort of review (if
any) is needed, the conditions under which update requests would
IAB & Kolkman Expires September 20, 2014 [Page 6]
Internet-Draft IANA framework March 2014
normally be granted or when they might not, the security requirements
of these interactions, etc. The entity performing this role may
delegate its policy responsibilities for part or all of the
parameters within the registry. Consequently, in this document the
word "policy" is used to refer to a specific course or principle of
action for administration of a technical resource maintained within
specific registries.
Key Responsibilities:
The Policy Role refers to the creation of the governing policies that
define how and when a registry can be updated or modified.
Primary Output:
A set of policies by which registries can be populated.
2.2. Evaluation Coordination Role
The Evaluation Coordination Role and the Maintenance/Publication Role
(below) comprise the actual day-to-day operation of a registry in
terms of servicing requests for registry additions or updates and
publishing the contents of the registry. These roles implement
processes that abide by the policies as defined by the Policy Role.
Key Responsibility:
Coordinate, operate, and process the timely evaluation of
registration requests based on policies set by the Policy Role.
Primary Output:
A smoothly functioning system in which requests for registry updates
are submitted and are evaluated and processed in a manner consistent
with the policy guidance with the results recorded and published as
appropriate. In some cases, the evaluation of requests is a
straightforward task requiring little subjective evaluation, whereas
in other cases evaluation is more complex and requires subject matter
experts as defined by the relevant policy guidance.
Relation to other roles and activities:
The output of the evaluations is input to the process of assignment,
delegation, and/or population of the registries as performed by the
entity in the Maintenance/Publication Role (Section 2.3). The
evaluations are performed based on the policies as defined by the
Policy Role. The coordination of the evaluation is different from
the evaluation of a request itself: the Evaluation Coordination Role
IAB & Kolkman Expires September 20, 2014 [Page 7]
Internet-Draft IANA framework March 2014
handles the request for allocation or maintenance of a record and
may, under guidance of and in coordination with the entity fulfilling
the Policy Role, delegate the actual evaluation to a third party.
2.3. Maintenance/Publication Role
Key Responsibility:
The maintenance of the registries' content: allocating or assigning
parameters after positive evaluation and based on established
policies, keeping appropriate record of transactions, and making the
registries widely and freely available to the extend possible, to
encourage protocol usage in conformance with the specifications.
Primary Output:
Easy and convenient access to registry contents, with additions and
updates appearing in a timely manner.
Note:
Registry maintenance and publication are strictly mechanical
functions. In practice the entity that performs those functions will
often perform some or all of the responsibilities of the Evaluation
Coordination Role. For instance, verification that an application/
registration request is correct is an Evaluation Coordination
responsibility that can reasonably be explicitly assigned to the
entity performing the Maintenance/Publication Role by the entity that
performs the Policy Development Role while evaluation of technical
content is usually delegated to technical experts.
2.4. The Oversight Role
Description:
The oversight role refers to a high-level responsibility for ensuring
that the other three roles are operating satisfactorily. Oversight
involves stepping in if significant changes are needed in the
policies, evaluation coordination, maintenance, or publication of a
registry.
Key Responsibility:
Ensure that policies and the implementation of registries are aligned
in a way that supports the coherent long-term development and use of
shared Internet resources. Coordinate with entities with similar
roles for other registries.
IAB & Kolkman Expires September 20, 2014 [Page 8]
Internet-Draft IANA framework March 2014
The oversight role is normally isolated from policy development.
That said, the entity performing the Oversight Role may serve to
resolve appeals related to policies or ratify developed policies.
3. Key principles of the IANA framework
The following key principles underscore the successful functioning of
the framework:
Separation of Roles: The Policy, Evaluation Coordination,
Maintenance/Publication, and Oversight roles should be separate or
separable. A clear distinction between the roles enhances the
transparency and makes it clearer who is accountable to whom.
Delegation: It should be possible to delegate any of the roles for
registries or parts thereof.
Accountability and transparency: The entities fulfilling the roles
are accountable to the materially concerned parties and the wider
community. The entities fulfilling the Oversight Role are
directly accountable to the wider community, although not all of
the entities fulfilling the other roles must be. By implication,
the entities fulfilling Oversight Role must maintain the highest
possible standards of transparency and be open to input and
review.
Stable and Predictable: Stable and predictable implementation of the
Internet registries function is important for establishing global
trust.
4. Discussion
4.1. On Separation of the roles
For many registries there is a de-facto separation of the Policy Role
and the Evaluation Coordination Role that takes place at
implementation. While this has never been an explicit requirement,
it seems that splitting those roles can expose instances where
policies lack of clarity, which provides helpful feedback to allow
those policies to be improved. In addition, having the Policy,
Oversight and the Evaluation Coordination Roles separated prevents
the risks of the Evaluation Coordination Role from being burdened
with (perceptions of) favoritism and unfairness.
IAB & Kolkman Expires September 20, 2014 [Page 9]
Internet-Draft IANA framework March 2014
4.2. On Delegation
Most, if not all, protocol parameter registries were created by the
IETF or its predecessors. Today, most IETF protocols paramaters
registries are maintained by the IANA at ICANN. However, nothing in
this framework prohibits the delegation of the Oversight, Policy,
Evaluation Coordination, or Maintenance/Publication role (or any
combination of these) of specific protocol parameter registries to
other organizations. In some circumstances, that may be desirable
and allow improved registry management for the good of the global
Internet community.
Delegation of an IANA registry may be desirable for several reasons,
including support for more inclusive registry policy development,
distributing registry operations globally, and accommodating public
policy considerations in registry management. While delegation of an
IANA registry in these situations can improve the registry service
received by the global Internet community, it is not guaranteed to do
so and hence it is incumbent upon the IAB to have clear guidelines
for successful IANA registry delegation. Such guidelines are out of
scope for this document.
Examples for registries where the responsibility for developing
policy has been delegated in whole or in part include the assignment
of domain names and the assignment of Internet Protocol (IP) address
blocks (both considered policy issues by [RFC2860]), and the
autonomous system (AS) number registry [RFC7020]. [RFC2860]
demonstrates that that delegation can be very specifically bounded:
"Note that (a) assignments of domain names for technical uses (such
as domain names for inverse DNS lookup), (b) assignments of
specialised address blocks (such as multicast or anycast blocks), and
(c) experimental assignments are not considered to be policy issues
[...]". These special-purpose names and addresses are assigned in
the same manner as protocol parameters except that coordination is
needed during policy setting and actual assignment of the values.
The oversight bodies may facilitate the coordination. Also see
Policy Examples 2 and 3 in Section 5.1.
4.3. Accountability
Any entity performing one of the roles defined in this framework is
to be held accountable for its responsibilities. Accountability of
each entity needs to be expressed in terms of 'who' and 'how'; to who
is the entity accountable and by which mechanisms is the entity being
held accountable. In other words registry policy development and
registry operations need to be "accountable" to the affected
community.
IAB & Kolkman Expires September 20, 2014 [Page 10]
Internet-Draft IANA framework March 2014
In practice accountability mechanisms may be defined by memoranda of
understanding or through contractual service level agreements (SLA)
between implementing entities and the oversight body while the
oversight bodies are being held accountable through community review
mechanisms, for instance through recall and appeal processes.
For example: For protocol parameters the general oversight over the
IANA function is performed by the IAB as a chartered responsibility
from [RFC2850] (also see Section 5.4). In addition the IAOC, a body
responsible for IETF administrational and financial matters,
[RFC4071] maintains an SLA with ICANN, thereby specifying the
operational requirements with respect to the coordination of
evaluation, and the maintenance and publication of the 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].
Accountability mechanisms can vary depending upon the actual
distribution of responsibilities (i.e.: how much is separated, how
much is delegated).
4.4. On the Ability to create Internet Registries
As with the IETF and the corresponding IANA Protocol registries,
other standards bodies (and other institutions) have long histories
of defining and creating registries and the parameters, tables, and
other values that make them up. Those normal practices may obviously
extend to registries and their contents for use on the Internet.
This document does not prescribe how those registries are governed.
The (wider) IETF has the authority to create new IETF Protocol
Parameter registries as described in [RFC6220]. The IETF also has
the authority to create registries that pertain to the Domain Name
System, but only for specify technical use [RFC6761]. Finally the
IETF has the (exclusive) authority to make technical assignment for
Number Resources out of the currently reserved address space
([RFC2860] and [RFC4291]).
5. Examples
5.1. Policy Examples
Not coincidentally, the following 3 examples map to how the IANA
registration functions are currently organized: IETF Protocol
Parameter Registries, Number Resources and Domain Names.
IAB & Kolkman Expires September 20, 2014 [Page 11]
Internet-Draft IANA framework March 2014
5.1.1. IETF Protocol Parameter Registries
The IETF, through the IESG (see [RFC6220] section 2.3), acts in this
role when in the "IANA Considerations" sections of its RFCs it
specifies the creation of a new registry, specifies initial entries,
and specifies a policy for adding additional entries to the registry
in the future. [RFC5226] provides guidance and terminology that has
proven useful within the IETF for describing common policies for
managing its registries. Those terms include "Private Use",
"Hierarchical allocation", "First Come First Served", "Expert
Review", "Specification Required", "IESG Approval", "IETF Consensus",
and "Standards Action". The IETF uses these and, if needed, other
templates to define the policy through which registries are
populated.
5.1.2. Number Resources
IP address allocation and the associated policy development is
distributed too. For instance, the IETF has defined an IPv6 address
range called unicast addresses. For a fraction of that address range
ICANN has been delegated change control (see [RFC3513] section 4 for
details and [GlobAddrPol] for examples). The change control is
further delegated to the Regional Internet Registries (RIRs) which,
guided by policies set by the regional communities, delegate change
control even further e.g., to Local Internet Registries.
5.1.3. Domain Names
The Domain Name System (DNS) protocol allows for hierarchical
maintenance of the domain name registries, and publication thereof.
ICANN is currently responsible for change control at the root zone
which includes setting and maintaining policies for that zone.
Change control, policy control, and publication authority follows the
DNS hierarchy; although ICANN is the authoritative entity in the
policy role for the root zone, it is not authoritative for all
domains below the root. For example the IETF sets the policy for
determining which names are allocated in the ietf.org zone. For
country code top-level domains (ccTLD) the policies are set by the
ccTLD registry in coordination with local community, local
regulator(s), and/or other national bodies. Even the policy for
assignment of names within the root is subject to nuances. For
instance, ICANN has reserved two letter top-level domains for the use
as country and territory code Top Level Domains (ccTLDs). The
assignment of two-letter codes themselves (that may consecutively be
used as DNS top-level domains) is done by ISO TC46/WG2 and are
maintained by the ISO 3166 maintenance agency [ISO.3166.2013]. The
selection of the operator of a ccTLD is currently governed by
[RFC1591], also see Section 5.4.4.
IAB & Kolkman Expires September 20, 2014 [Page 12]
Internet-Draft IANA framework March 2014
5.2. Evaluation Coordination Role Examples
5.2.1. IETF Protocol Parameters
As mentioned above, [RFC5226] provides terminology to define common
policies used by IETF registries associated with IETF protocols. One
of the policies that the Policy Role can impose for allocation from a
registry is "Expert Review". In this case a subject matter expert
will evaluate the allocation request and determine whether an
allocation will be made.
An alternative policy for allocation is the requirement for IETF
Consensus. This is where the IETF has first, in its Policy Role,
sets the policy to use its (policy) process to determine consensus
for a particular registry modification.
The IANA functions operator (currently operated by ICANN) is the
entity that, for the IETF, coordinates the evaluation of registration
requests against policies as set by the IETF.
5.2.2. Nubmer Resources
IP address allocation policy is developed bottom-up through the
Regional Internet Registry (RIR) communities. The RIR communities
perform the Policy Role while at the RIRs the Policy Evaluation Role
is performed by IP-Resource Analysts (or similar) that assess
allocation requests against the policies developed in the Region.
RIR staff often support or even initiate the policy development
process.
5.2.3. Domain Names
Generic TLD delegation policy is today developed bottom-up through
ICANN policy processes. As specified in ICANN's bylaws [ADDREF], the
ICANN Board of Trustees (BoT) oversees those process to perform the
Policy Role. The Policy Evaluation Role is performed under the
responsibility of the ICANN BoT; staff and various panels evaluate
applications for new generic top-level domains against the policies
developed via the ICANN Policy Development Processes. In addition,
ICANN staff often support these policy development processes.
5.3. Maintenance and Publication of Registry Content
IAB & Kolkman Expires September 20, 2014 [Page 13]
Internet-Draft IANA framework March 2014
5.3.1. IETF Protocol Parameters
ICANN, as the current IANA functions operator, publishes the protocol
parameters registries on the IANA website. Recently the plain-text
tables on that website have been augmented with tables in a
structured machine-readable format. The coordination of the
requirements for publication and the implementation of the technical
systems is part of the publication and maintenance responsibility.
5.3.2. Alternative publication mechanisms
[EDITORIAL NOTE: Add Reverse DNS and WHOIS content as examples of
publication and maintenance]
5.4. Oversight Examples
5.4.1. IETF Protocol Parameters
The Internet Architecture Board (IAB) is responsible for overseeing
the process used to create Internet Standards and coordinates with
the other entities that have the oversight role for Internet
Registries.
5.4.2. Nubmer Resources
Collectively, the communities served by the Regional Internet
Registries oversee the policy development for global Internet address
allocation policies.
5.4.3. Coordination - gTLDs vs special domain names
Collectively, the stakeholders involved in the ICANN policy
development processes serve to oversee the policy development for
generic TLD allocation processes.
Other examples of oversight around IETF protocols include the
coordination between the IAB and the ITU-T when the ENUM protocol
started to use E.164 identifiers (telephone numbers)[RFC3245].
Another example is the facilitation of coordination between the IETF
protocol development process and reservations of labels at the top-
level of the domain name space with RFC6761 as a recent example.
5.4.4. Coordination - ccTLD Administration
Some readers might have noticed that in the Policy Example in
Section 5.1.3 the policy by which ccTLD operators are selected refers
to RFC1591. RFC1591 was specified and published by the IANA, while
Internet was still an ARPA project and before ICANN and the IETF

existed. The IAB at the time maintained loose oversight of IANA but
had a different set of responsibilities. Should an update of RFC1591
or a declaration of the historic nature of that document be needed
then such action would most likely involve stewardship and
coordination by the IAB and ICANN.
6. Security Considerations
As discussed in Section Section 1.1 Internet Registries and the model
discussed in this document are critical to elements of Internet
security. However, this document simply discusses that model rather
than changing it and consequently does not directly affect the
security of the Internet.

A.1. Version Information
A.1.1. draft-iab-iana-framework-01 -> draft-iab-iana-framework-02
Reordered paragraphs in the Discussion to align them with the
order in the Key Principles. Also changed the order because
Accountability mechanisms may depend on the kinds of separation
and delegation applied.
Renamed the section titles for the examples from numbers to more
descriptive titles.
Significant rewording to improve readability based on feedback by
Alissa Cooper.
Added the paragraph talking about general use in Section 1.2 based
on feedback from John Curran.
A.1.2. draft-iab-iana-framework-00 -> draft-iab-iana-framework-01
Significantly reordered the document by pulling the examples out
of the descriptions of the roles and moving those to section
Section 5.
Split the "Implementation Role" into two different roles
explicitly: Evaluation and Maintenance. Both those roles can be
headed under Implementation aspects.
Refined text about te "what, who and why" and gave an overview in
section Section 1.2
Reworded the text in Section 4.2 to highlight that only the name
assignment is the policy aspect that has been delegated.
Similarly, in section Section 5.1 I tried to illustrate that even
within the domain name assignment in the root there are delegated
policies by introducing the ISO3166 reference.
IAB & Kolkman Expires September 20, 2014 [Page 18]
Internet-Draft IANA framework March 2014
Added Oversight Example 4 in Section 5.4 as an example of policy
that exists for over a few decades and for which an update would
need coordination
Nits and minor edits.
A.1.3. draft-kolkman-iana-framework-00 -> draft-iab-iana-framework-00
Added section "On Accountability" and "On Delegation".
Refined some of the phrasing based on a thorough review by David
Conrad"
Added a reference to [RFC7020] in Section 1.3 and clarified the
informative rather than normative nature of the examples.
Added section Section 3 and changed the name of section Section 4.
Nits and minor edits.
A.1.4. draft-kolkman-iana-framework-00
This draft is the result of a set of brainstorms in the IAB IANA
program, it does not claim to reflect any consensus.
A.1.5. TODO
o [RFC EDITOR: BCP10 reference [BCP10] needs to be formatted
correctly. The annotation hack used to list multiple RFCs that
make up BCP10 does not seem to work.]
