[ppml] Policy Proposal: IPv4 Transfer Policy Proposal

Jim,

Reading over 4.2 and 4.3 of the NRPM, I see lots of different conditions 
for different types of networks.  Specifically, the text in 4.2.2.1.3 
and 4.2.2.2.2 requiring that the requested IP address space will be 
utilized within three months refers to organizations justifying an 
initial allocation on the basis of their use of PA space, and is 
intended to minimize delay in renumbering out of PA space (if 
applicable) and beginning to use and route the new space.  As I read 
those sections, they don't require 100% utilization within three months.

However, in 4.2.4.3 and 4.2.4.4, it does appear that a new ISP that 
needs additional space before they've been an ARIN member for a year can 
only justify a three-month supply of addresses.  After that, they can 
get six months' worth.  In the case of end users, they can get over a 
year's worth of space according to 4.3.3.

Given all this confusion, I'd like to decouple the 8.4 transfer policy's 
transfer sizes somewhat from the allocation and assignment sizes in 4.2 
and 4.3, by adding the following bullet point to 8.4.2:

    * The transferee may request and receive a contiguous CIDR block
      large enough to provide a 12 month supply of IPv4 addresses.

That will preserve the requirement that need and efficient use are 
justified, but would bypass the sections of 4.2 and 4.3 concerned with 
preventing hoarding (intentional or otherwise).  My assumption here is 
that the cost of transferring addresses and a 12-month supply rule would 
act as a sufficient brake to prevent anyone from getting more addresses 
than they need for that timeframe.  The 12-month supply should also be 
sufficient, in concert with the one-block-every-6-months condition, to 
ensure that transferees get enough address space to limit unnecessary 
deaggregation.

Thoughts?

>>        including minimum allocation size (i.e. NRPM 4.2.2., 4.2.4.,

>>        ARIN service area, either as part of an address block assigned by
>>        IANA to ARIN, or as part of a legacy address block allocated
>>        within the ARIN service area.
>>      * There must exist no dispute as to the status of the IPv4 block or
>>        regarding the allocation or assignment of such block to the
>>        transferor.
>>      * The transferor may retain one contiguous address range out of
>>        their original allocation or assignment for their own use, and
>>        transfer the other contiguous address range.  If the address
>> range
>>        to be transferred consists of multiple non-aggregatable CIDR

>>        retained address range may not be further subdivided or
>>        transferred for a period of 12 months.
>>
>> 8.4.4    Fees
>>
>>      * Completion of a transfer requires payment of a transfer fee
>>        according to ARIN's schedule of fees.
>>      * The transferee will be subject to all future ARIN membership and
>>        service fees according to the transferee's total address

>>
>> 8.4.5    Pre-qualification
>>

>>
>> 8.7.      Record-keeping and Publication of Simple Transfers of IPv4
>> Addresses
>>
>> ARIN will develop and operate a listing service to assist interested
>> transferors and transferees by providing them a centralized location to
>> post information about IPv4 blocks available from prequalified
>> transferors and IPv4 blocks needed by prequalified transferees.
>>
>> After completion of the transfer, ARIN will update the registration
>> records pertaining to the IPv4 block at issue.  ARIN will adjust its
>> records as to the holdings of the transferor and transferee.
>>
>> After the transfer, ARIN will publish WHOIS data that reflects the
>> current allocation or assignment of the transferred block.  ARIN will
>> also make available information about any prior recipient(s) of such
>> block.  ARIN will also publish a log of all transfers, including block,
>> transferor, transferee, and date.
>>
>>
>> Rationale:
>>
>> The ARIN Board of Trustees asked the Advisory Council to consider a set
>> of questions around the depletion of the free pool of IPv4 addresses,
>> the transition to IPv6 for Internet address needs in the future, and
>> ARIN's possible role in easing the transition.
>>
>> Over the past few years the AC has spent a great deal of time reflecting
>> on these issues as a group, as individuals, and in consultation with
>> the community. One outcome of this process is this policy proposal,
>> which the AC is submitting for consideration at the next meeting. We are
>> proposing some changes to existing ARIN policy regarding the transfer of
>> IP address block registrations between subscribers, which will allow for
>> the emergence of trade in IPv4 address space, with ARIN to provide a
>> listing service for address blocks available for transfer under the
>> liberalized policy.  We are aware that this proposal, if adopted, will
>> mark a major change in ARIN's role in the community and the Internet.
>>
>> This policy proposal would create a transfer mechanism for IPv4 number
>> resources between those who have excess resources and those who have a
>> need, thereby allowing ARIN to continue to serve its mission after IANA
>> free pool exhaustion.  This proposal would also set conditions on such
>> transfers intended to preserve as much as possible the existing policy
>> related to efficient, needs-based resource issuance, and would leverage
>> ARIN's extensive control systems, audit trails, and recognized position
>> as a trusted agent to avoid speculation and hoarding and diminish the
>> likelihood and extent of an uncontrolled 'black market' where the risk
>> and potential for fraud is immeasurably higher.
>>
>> Many of the transfer conditions are self-explanatory, but some worth
>> highlighting are that:
>>
>>      * To discourage speculation, a waiting period (proposed at 24
>>        months) is required before a transferee (or ordinary resource
>>        recipient) can become a transferor, or vice versa.
>>      * Transferees must qualify for IPv4 space (just as they do today
>>        when getting it from ARIN) before they can receive address space
>>        by transfer, or solicit space on a listing service.
>>      * To discourage unnecessarily rapid growth of routing tables, an
>>        allocation or assignment may not be arbitrarily deaggregated.  To
>>        allow a transferor to downsize within their existing space, they
>>        may split off a contiguous address range, once every 12 months,
>>        and transfer the resulting netblock(s), which are subject to
>>        ARIN's minimum allocation size, to one or more transferee(s).
>>      * A transferee may receive one transfer every 6 months, so they'll
>>        be incented to transfer a block appropriately sized for their
>>        needs, which will further discourage deaggregation and keep
>>        smaller blocks available for smaller organizations.
>>
>> The proposal would also have ARIN develop and operate a listing service
>> to facilitate transfers and provide an authoritative central source of
>> information on space available and requested for transfer.  It would not
>> prohibit private party transactions, but would require that potential
>> transferors and transferees be pre-qualified first, so that neither
>> party will encounter any unexpected surprises when they ask ARIN to
>> process the transfer.
>>
>> Timetable for implementation: Immediately, with most aspects of policy
>> taking effect upon IANA exhaustion, per the policy text.
