This is definitely along the right track!  I'll think more about it over the weekend.

Take care

Subject: [arin-ppml] Simplified IPv6 policy

Here's an attempt at how we might simplify IPv6 policy, incorporating many of the ideas we've discussed recently.  It's much simpler than current policy, but is still quite long.  It's also late, so I reserve the right to make mistakes, and to disagree with myself later.  :-)

Delete "6.1 Introduction"
This is all historical.

Delete "6.2 Definitions"
The definitions we need are all defined in section 2.

Leave 6.3 as is (renumber to 6.1)
I think these still accurately reflect the Goals we want our policy to follow.

Move 6.4.1 to 1.1.  Retitle to "Number resources not to be considered property" and update text per below.
This is a principle more general than just IPv6, and needs to be updated to be ARIN-specific and refer to the RSA.

Delete 6.4.2 - 6.4.4
These principles don't seem worthy of elevation to special status.

Replace 6.5 Policies for allocations and assignments with text below (renumber to 6.2)
This seems to be where most of the changes and simplification are needed.

Delete 6.6 References
This is all historical, and doesn't need to be part of the NRPM.

Delete 6.7 Appendix A: HD-Ratio
As above, we can let the HD-Ratio guide policy without making people do the math.

Delete 6.8. Appendix B: Background information
This is all historical

Move 6.9 and 6.10 into below

Replacement text:

1.1.  Number resources not to be considered property

It is contrary to the goals of this document and is not in the interests of the Internet community as a whole for address space to be considered freehold property.

The policies in this document are based upon the understanding that globally-unique number resources are licensed for use rather than owned. Specifically, IP addresses and ASNs will be allocated and assigned on a license basis, with licenses subject to renewal on a periodic basis. The granting of a license is subject to specific conditions applied at the start or renewal of the license, as definied in the ARIN Registration Services Agreement.

Note that when a license is renewed, the new license will be evaluated under and governed by the applicable number resource policies in place at the time of renewal, which may differ from the policy in place at the time of the original allocation or assignment.

6.2.  Policies for IPv6 allocations and assignments

6.2.1.  Allocations and assignments
To meet the goal of Fairness, ARIN makes both allocations and assignments according to common criteria.  Allocations are made to LIRs, and assignments to certain end users.

6.2.2.  Assignments from LIRs/ISPs
End-users are assigned an end site assignment from their LIR or ISP. The exact size of the assignment is a local decision for the LIR or ISP to make, using a minimum value of a /64 (when only one subnet is anticipated for the end site) up to the normal maximum of /48, except in cases of extra large end sites where a larger assignment can be justified.

The following guidelines may be useful (but they are only guidelines):

   * /64 when it is known that one and only one subnet is needed
   * /56 for small sites, those expected to need only a few subnets over the next 5 years.
   * /48 for larger sites

For end sites to whom reverse DNS will be delegated, the LIR/ISP should consider making an assignment on a nibble (4-bit) boundary to simplify reverse lookup delegation.

ARIN is not concerned about which address size an LIR/ISP actually assigns. Accordingly, ARIN will not request the detailed information on IPv6 user networks as in IPv4, except for the purpose of measuring utilization as defined in this document.

6.2.3. Allocations and assignments from ARIN  Goals
To balance the goals of Aggregation, Conservation, Fairness, and Minimized Overhead, ARIN normally makes allocations only in the discrete sizes of /48, /40, /32, /28, or /24 or larger.  Each organization or discrete network may qualify for one allocation or assignment of each size, and must pay fees according to ARIN's <a href="https://www.arin.net/fees/fee_schedule.html">fee schedule</a>
for each size assigned.  X-Small (/48)
To qualify for a /48 allocation or assignment, an organization must:
   * Serve at least 500 hosts, if multihomed; or
   * Serve at least 1000 hosts; or
   * Demonstrate efficient utilization of all direct IPv4 assignments and allocations, each of which must be covered by any current ARIN RSA; or
   * Be a critical infrastructure provider of the Internet, including public exchange points, core DNS service providers (e.g. ICANN-sanctioned root, gTLD, and ccTLD operators) as well as the RIRs and IANA; or
   * Qualify for a Micro-allocations for Internal Infrastructure per Critical Infrastructure
Organizations qualified as critical infrastructure providers may be granted multiple /48 allocations in certain situations.  Exchange point allocations MUST be allocated from specific blocks reserved only for this purpose. All other micro-allocations WILL be allocated out of other blocks reserved for micro-allocation purposes. ARIN will make a list of these blocks publicly available. Exchange point operators must provide justification for the allocation, including: connection policy, location, other participants (minimum of two total), ASN, and contact information. ISPs and other organizations receiving these micro-allocations will be charged under the ISP fee schedule, while end-users will be charged under the fee schedule for end-users. This policy does not preclude exchange point operators from requesting address space under other policies. Micro-allocations for Internal Infrastructure
Organizations that currently hold IPv6 allocations may apply for a /48 micro-allocation for internal infrastructure. Applicant must provide technical justification indicating why a separate non-routed block is required. Justification must include why a sub-allocation of currently held IP space cannot be utilized. Internal infrastructure allocations must be allocated from specific blocks reserved only for this purpose.  Small (/40)
To qualify for a /40 allocation or assignment, an organization must qualify for two or more /48s.  Medium (/32)
To qualify for a /32 allocation or assignment, an organization must:
   * Qualify for 100 or more /48s; or
   * Be an existing, known LIR; or
   * Have a plan to provide IPv6 connectivity to other organizations and assign at least 100 end-site assignments to those organizations within 5 years.  Large (/28)
To qualify for a /28, an organization must demonstrate the need to make assignments and/or reallocations equal to at least 20,000 /48s.  X-Large (/24 or larger)
Allocations or assignments of /24 or larger may be made only in exceptional cases, to organizations that require more than a /28, and have submitted documentation that reasonably justifies the request. If approved, the allocation size will be based on the number of existing users and the extent of the organization's infrastructure.

6.3. Registration

When an organization holding an IPv6 address allocation makes IPv6 address assignments, it must register assignment information in a database, accessible by RIRs as appropriate (information registered by ARIN may be replaced by a distributed database for registering address management information in future). Information is registered in units of assigned /56 networks. When more than a /56 is assigned to an organization, the assigning organization is responsible for ensuring that the address space is registered in an ARIN database.

IRs shall maintain systems and practices that protect the security of personal and commercial information that is used in request evaluation, but which is not required for public registration.

6.3.1. Residential Customer Privacy (2003-3)

To maintain the privacy of their residential customers, an organization with downstream residential customers may substitute that organization's name for the customer's name, e.g. 'Private Customer - XYZ Network', and the customer's street address may read 'Private Residence'. Each private downstream residential reassignment must have accurate upstream Abuse and Technical POCs visible on the WHOIS record for that block.

6.3.2. Reverse lookup

When ARIN delegates IPv6 address space to an organization, it also delegates the responsibility to manage the reverse lookup zone that corresponds to the allocated IPv6 address space. Each organization should properly manage its reverse lookup zone. When making an address assignment, the organization must delegate to an assignee organization, upon request, the responsibility to manage the reverse lookup zone that corresponds to the assigned address.
