Here's some straw man text to replace what's in prop 2013-4.
Discussion requested.

Section 0: Principles and Goals of this Regional Internet Registry

0.1 Uniqueness

It is this registry's purpose to document Internet number resource
allocation, reallocation, assignment, and reassignment for use on an
Internet. This registry does not provide numbers for use solely inside
a single organization's internal network. This registry does not set
practices or policy for shared uses of unicast or non-unicast numbers.
Organizations requiring such numbers are encouraged to visit RFC 1918
and the IETF.

Unique registration is necessary to the successful technical operation
of any Internet. The registry's process must guarantee that no two
organizations are correctly using the same unicast network address on
the Internet.

0.2 Sustainability

The registry is charged with providing number resources for the entire
lifespan of the protocols which use those number resources. Registry
policy must provide for the availability of number resources for
then-reasonable use via the registry through every phase of a
protocol's widespread use.

0.2.1 Early Phase

A protocol's early phase starts with the registry taking
responsibility for a protocol's number resources. The phase continues
until the proportion of the protocol's use leads all similar protocols
on the public Internet. During the early phase, priority is placed on
getting out of the users' way. The registry must studiously avoid
policies and practices which even mildly impair the protocol's

While conservation is a distant concern, care should be taken to avoid
allocating more than 20% of a protocol's usable number resources prior
to the mainline phase.

0.2.2 Mainline Phase

A protocol's main line phase starts when the protocol's use first
pulls ahead of the similar protocols in proportion of use on the
public Internet. The phase continues until more than 90% of the usable
number resources have been allocated or otherwise reserved. During the
main line phase, conservation becomes a growing consideration.
Conservation efforts should endeavor to prevent the occurrence of a
zero sum phase by slowing resource consumption to a level where 90%
allocation will not be achieved prior to the protocol's obsolescence.

0.2.3 Zero Sum Phase

A protocol's zero sum phase begins once 90% of the usable number
resources have been allocated. During the zero sum phase, registry
policies must facilitate the movement and if necessary cause number
resources to move from underutilized applications to more effective
uses. The registry must not abdicate its responsibility to ensure the
continued availability of number resources to the third parties to
whom it previously allocated those resources.

0.3 Support Scalable Routing

Policies for managing Internet number resources must facilitate
scalable routing. This scalability is necessary to ensure continued
operation of the Internet.

We observe that the Border Gateway Protocol (BGP) has been the core
routing technology in use on the Internet since ARIN's inception with
no end in sight. BGP scalability is achieved only by announcing CIDR
aggregates of downstream customer routes which are as large as

0.3.1 ARIN does not set Internet Routing Policy

While ARIN number policy is informed by current routing technologies
and routing policy choices made by Internet Service Provides, ARIN
does not make policies about how routing must or must not be done.
Allocation or assignment of addresses by ARIN in no way guarantees
that those addresses will be routeable on the public Internet.

0.4 Fairness

This registry supports the concept of equal access for all. The phased
nature of sustaining a protocol's existence and the need to support
scalable routing necessarily introduce some fundamental unfairness
into the registry's policies and processes. Where not documentably
necessary to achieving those principles, registry practices which
could reasonably be interpreted as favoring one registrant over
another due to size, the nature of the registrant or his business,
location within the service territory or similar factors are to be

0.5 Cooperation

Where reasonable and equitable the registry should cooperate with its
sister registries in other service territories and seek consistent,
uniform practices across the world.

0.6 Stewardship & Conflict of Goals

Where these principles conflict, priority should go first to
uniqueness and then sustainability.
