ARIN-prop-190 Merge IPv4 ISP and End-User requirements

Proposal Originator: Dan Alexander

Date: July 22, 2013

Problem Statement: This proposal attempts to reconcile the differences
in requirements for obtaining PA and PI IPv4 address resources.

Policy statement:

Short list of changes with details explained below.

* Remove section 4.1.1 Routability
* Rewrite section 4.1.5 Determination of resource requests
* Remove section 4.1.7 RFC2050
* Rename section header 4.2 Allocations to ISPs (Requiments for Requesting
Initial Address Space)
* Remove section header 4.2.1 Principles and promote subsections
* Rewrite section 4.2.1.1 Purpose
* Remove section 4.2.1.4 Slow start
* Remove section 4.2.1.5 Minimum allocation
* Remove section 4.2.2.1 Standard or non-multihomed (and subsections)
* Remove section 4.2.2.2 Multihomed (and subsections)
* Rewrite section 4.2.2 with combined wording to replace sections that are
being removed. See details below.
* Replace section 4.2.4 ISP Additional Requests (and subsections)
* Move original section 4.3.5 to new combined section 4.2.7. (unchanged
text)
* Remove section 4.2.5 Web Hosting Policy
* Remove section 4.3 End-users-Assignments to end-users (and subsections)
* Remove section 4.9 Minimum allocation for the Caribbean and North
Atlantic Islands (and subsections)

Summary of requirement changes:

Minimum allocation for a single-homed ISP is reduced from a /20 to /22.
Minimum allocation for a multi-homed ISP is reduced from a /22 to a /24.
The distinction between subscriber members who are before or after a one
year anniversary is removed.
Minimum assignments for a single-homed end user is reduced from a /20 to a
/22.
The requirement that multi-homed, end-user assignments smaller than a /20
be made from a block reserved for that purpose is removed.
The utilization requirements on an initial end-user assignment changes
from 25% immediate, 50% within one year to 80% within three months. This
is offset by the lowering of the minimum block size requirement for
single-homed networks.
The timeframe for additional ISP allocations is changed from three months
back to one year.
The special section for the Caribbean region is integrated into the same
requirements as the rest of the region with the existing /22 and the
addition of an option for a multi-homed /24.

Details:

* Remove section 4.1.1 Routability
In merging the PI and PA requirements this section seems unnecessary in
the newer version. It is also not necessary for the NRPM to suggest who or
where an organization obtains resources.

* Renumber and rewrite section (4.1.5 Determination of IP address
allocation size)

Remove: “Determination of IP address allocation size is the responsibility
of ARIN.”

Replace with: (4.1.1 Determination of resource requests)
“Determining the validity of the amount of requested IP address resources
is the responsibility of ARIN.”

Rationale: The specific use of “allocation” does not propagate to end-user
assignments in the proposed, merged instance. It is also an attempt to
clarify that it is the validity of the request that is more the focus than
the amount of resources requested. This does not prevent ARIN from
suggesting that a smaller block would be justified where a larger one
would not, but also does not suggest that it is ARIN’s sole discretion to
judge the size of the blocks needed.

* Remove section 4.1.7 RFC2050
With RFC2050 being updated the debate needs to occur whether this section
should be retained in the principles of the IPv4 policy section. This may
be better addressed by ARIN-2013-4.

* Rename section header (4.2 Allocations to ISPs Requiments for Requesting
Initial Address Space)
New section name: 4.2 Resource Requirements

* Remove section 4.2.1 Principles and promote subsections
In merging the requirements of section 4.2 and 4.3 this section becomes
overly complicated and this was an attempt to simplify.

* Replacement section (4.2.1 Purpose)

Remove: “ARIN allocates blocks of IP addresses to ISPs for the purpose of
reassigning that space to their customers.”

Replace with: “ARIN provides blocks of IP addresses to network operators
for the purpose of using these resources on their network.”

Rationale: The distinction is removed between end-users and ISP’s to
provide a unified set of requirements.

* Remove section 4.2.1.4 Slow start
In an attempt to merge ISP and end user assignments it was desired to not
take any functionality away that already existed for one or the other and
balance this with transfer requirements.

* Remove section 4.2.1.5 Minimum allocation
In an attempt to merge ISP and end user assignments it was desired to not
take any functionality away that already existed for one or the other and
balance this with transfer requirements.

* Remove section 4.2.2.1 Standard or non-multihomed (and subsections)
This is being replaced with the merged text in the proposed section 4.2.5.

* Remove section 4.2.2.2 Multihomed (and subsections)
This is being replaced with the merged text in the proposed section 4.2.5.

* Rewrite section 4.2.2 with combined wording to replace sections that are
being removed.

Replacement section (4.2.5 Minimum Size and Utilization)

A /24 is the minimum sized block to be provided to a multi-homed network.

A /22 is the minimum sized block to be provided to a single-homed network.

Through appropriate documentation like reassignment information of blocks
from an upstream provider, or other means requested by ARIN, it must be
shown how an initial block would be 80% utilized within three months. It
must be agreed upon that the newly requested IP address space will be used
to renumber out of any current addresses, which will be returned to their
upstream provider(s). Blocks smaller than the minimum should be obtained
from an upstream provider.

* Replace section 4.2.4 ISP Additional Requests (and subsections)

Replacement section (4.2.6 Subsequent Requests)

All previously received IP address resources must be efficiently utilized,
and at least 80% of their most recent IP block(s) in order to obtain
approval of receiving up to an additional 12-month supply of IP address
resources.

* Move original section 4.3.5 to new combined section 4.2.7. (unchanged
text)

* Remove section 4.2.5 Web Hosting Policy
This is being replaced with the merged text in the proposed section 4.2.5
and 4.2.6

* Remove section 4.3 End-users-Assignments to end-users (and subsections)
This is being replaced with the merged text in the proposed section 4.2.5
and 4.2.6

* Remove section 4.9 Minimum allocation for the Caribbean and North
Atlantic Islands (and subsections)
This is being replaced with the merged text in the proposed section 4.2.5
and 4.2.6

6. Comments: The network resource policy manual has become an
   unnecessarily complex document as a result quickly evolving requirements.
   This proposal is an attempt to simplify one part of the document in a way
   that is easily understood even though it intentionally leaves other parts
   unresolved. This was done to keep the scope to something that could
   realistically be discussed.

Timetable for implementation: Immediate
