Below is an updated copy of my Simplified IPv6 Policy proposal, which 
takes into account suggestions made on the list so far.



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 

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
/We can let the HD-Ratio guide policy without making people like David's 
grandma 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 as 
defined in the ARIN Registration Services Agreement.

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.

6.2.3. Allocations and assignments from ARIN Goals

To balance the goals of Aggregation, Conservation, Fairness, and 
Minimized Overhead, ARIN normally issues IPv6 addresses 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 fee 
schedule [1] <https://www.arin.net/fees/fee_schedule.html> for each size 
issued. X-Small (/48)

To qualify for a /48 allocation or assignment, an organization must:

    * Be multihomed, per section 2.7, and qualify for an ASN per section
      5; 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
    * Qualify for a Micro-allocations for Internal Infrastructure per Micro-allocations for Internal Infrastructure /(Copied from 
NRPM 6.10.2)/

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 /(Copied from NRPM 6.5.5)/

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.

6.3.1. Residential Customer Privacy /(Copied from NRPM

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 /(Copied from NRPM 6.5.6)/

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.
