Recommended Draft Policy ARIN-2013-4
RIR Principles

Date: 16 October 2013

Policy Statement (16 October 2013):

Section 0: Principles and Goals of the American Registry for Internet Numbers (ARIN)

0.1. Registration

The principle of registration guarantees the uniqueness of Internet number resources.

Provision of this public registry documenting Internet number resource allocation, reallocation, assignment, and reassignment is necessary:
a) to ensure uniqueness,
b) to provide a contact in case of operational/security problems,
c) to provide the transparency required to ensure that Internet number resources are efficiently utilized, and
d) to assist in IP allocation studies.

0.2. Conservation

The principle of conservation guarantees sustainability of the Internet through efficient utilization of unique number resources.

Due to the requirement for uniqueness, Internet number resources of each type are drawn from a common number space. Conservation of these common number spaces requires that Internet number resources be efficiently distributed to those organizations who have a technical need for them in support of operational networks.

0.3. Routability

The principle of routability guarantees that Internet number resources are managed in such a manner that they may be routed on the Internet in a scalable manner.

While routing scalability is necessary to ensure proper operation of Internet routing, allocation or assignment of Internet number resources by ARIN in no way guarantees that those addresses will be routed by any particular network operator.

0.4. Stewardship

The principle of stewardship guarantees the application of these principles when managing Internet number resources.

The fundamental purpose of Internet number stewardship is to distribute unique number resources to entities building and operating networks thereby facilitating the growth and sustainability of the Internet for the benefit of all.

It should be noted that the above goals may sometimes be in conflict with each other and with the interests of individual end-users or network operators. Care must be taken to ensure balance with these conflicting goals given the resource availability, relative size of the resource, and number resource specific technical dynamics, for each type of number resource.


a. Timetable for implementation: immediately

b. I believe that it would be beneficial for IANA to adopt these principles as well, and encourage the community to consider a global policy proposal.

Text removed from third paragraph of Stewardship above:

For example, Conservation often requires greater consideration in IPv4 address distribution due to the limited size of the address space, Routability has a higher weight for the massive IPv6 address space, and AS numbers place the highest value on Registration because they come from a moderately sized pool and are not subject to aggregation.

AC’s assessment of conformance with the Principles of Internet Number Resource Policy:

ARIN-2013-4 “RIR Principles” was moved to recommended draft policy status for adoption discussion at ARIN 32. The majority of the AC believes that documenting the existing principles under which ARIN operates uniquely enables fair and impartial number resource administration and that these principles are technically sound, based on their history and heritage. The AC also notes that the current text, after being revised to incorporate staff and community feedback, now has community support.

Problem Statement:

The original text in RFC 2050 both “describes the registry system for the distribution of globally unique Internet address space and registry operations” and provides “rules and guidelines [principles] governing the distribution of this address space.”

The currently proposed update (RFC2050bis) “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” and “provides information about the processes for further evolution of the Internet Numbers Registry System.”

This means that the guiding principles of stewardship are not currently being carried forward into the new document. The goals of Conservation (efficient utilization based on need), Routability (hierarchical aggregation), and Registration (uniqueness) are as important, if not more so, now that the transition to IPv6 is upon us. This can be rectified by documenting these principles in RIR policy.


ARIN Staff and Legal Assessment

Principles and Goals of the Internet Registry System

DATE: 17 September 2013

  1. Summary (Staff Understanding)

This policy would add text to the NRPM which codifies the guiding principles of the registry system as registration, conservation, routability, and stewardship.


A. ARIN Staff Comments

· This proposal text is clear.

· Staff notes that the proposal does not appear to change any existing processes or procedures.

· It appears that the author’s intent is to add these statements as guiding principles into the NRPM.

· Their inclusion into the policy manual will make it more clear to the community the principles under which ARIN has operated.

· For reference, the term “Registration” already exists in NRPM as follows:
· Registration - Refers to ISPs providing reassignment information, so it’s not applicable.
· 6.3.3. Registration - This section has some overlap, could be reduced, but also refers to privacy.
· 6.5.5. Registration - Refers to reassignment information, so it’s not applicable.

· The term “Conservation” exists already in 6.3.5 but is different and specific to IPv6.

· The addition of the term “Routability” would make a portion of NRPM 4.1.1 redundant.

· The term “Stewardship” would add that word anew to the NRPM.

· The statement about conflicting goals should not refer to any specific type of number resource if it is a principle.
o Suggestion - Allow the specific conflicts to exist in the particular section. Remove everything from “For example” on.

· Note also that NRPM 6.3.8 already talks about conflict of goals, noting “aggregation” as the most important goal for IPv6.

· Staff suggests different placement/numbering, in particular, moving the introduction text up into the Abstract section before the TOC, thus freeing up Section 1 for “RIR Principles”.

· It is worth noting that the ARIN Policy Development Process contains the following:
“4. Principles of Internet Number Resource Policy” Internet number resource policy must satisfy three important principles, specifically: 1) enabling fair and impartial number resource administration, 2) technically sound (providing for uniqueness and usability of number resources), and 3) supported by the community.”

Furthermore that the RFC 7020 contains references to “1) Allocation Pool Management, 2) Hierarchical Allocation, and 3) Registration Accuracy”. It is suggested that the policy text be reviewed to avoid duplication with these existing principles.

B. ARIN General Counsel - Legal Assessment

The text of the policy does not create a material legal issue for ARIN. Any effort like this to accurately incorporate in writing the concepts that animate ARIN’s activity is a positive development.

  1. Resource Impact

This policy would have minimal resource impact from an implementation aspect. It is estimated that implementation would occur within 3 months after ratification by the ARIN Board of Trustees. The following would be needed in order to implement:

A. Updated guidelines

B. Staff training
