This is the latest draft for the revision of 2005-1. We
are interested in feedback before we submit it as the
formal revision.  For qualification purposes it is much
closer to the original 2005-1.  Unlike any previous version
assignment size is variable (explained in the justification

Add new definition in section 6.2 of the NRPM:

   6.2.10 Physical Location

     A distinct physical location is identified by a unique street
     address within an organization.  Different apartment, suite, room,
     unit or other similar identifiers at the same address for the same
     organization are not considered unique.

Add new subsection in section 6.5 of the NRPM:

   6.5.8. Direct assignments to large/multihomed end sites To qualify for a direct assignment, an
              organization must:

       a) not be an IPv6 LIR;
       b) meet at least ONE of the following requirements:

         1) Have an IPv4 assignment or allocation directly from an RIR,
            the IANA or legacy registry
         2) Qualify for an IPv4 assignment or allocation from ARIN under
            the IPv4 policy currently in effect
         3) Be currently multihomed using IPv6 to two or more separate
            LIR's using at least one /48 assigned to them by each LIR. Direct assignment size to large/multihomed end sites

         Organizations that meet the direct end site assignment criteria
         are eligible to receive a direct assignment.  The size of the
         assignment is based on the number of distinct physical locations
         where the assignment will be used. The following table will be
         used to determine the assignment size:

          | Locations  | Assignment |
          |       1-13 |    /44     |
          |     14-183 |    /40     |
          |   184-2486 |    /36     |
          | 2487-33688 |    /32     |

          For organizations requesting an assignment shorter than /32 the
          HD ratio method will be used.  For the HD ratio the utilization
          threshold is based on the numbmer of distinct physical
          locations that will be using IPv6.  The HD ratio used will be
          the same as in section Subsequent Assignment Size

           An organization may receive an additional assignment when it
           has grown to include enough distinct physical locations to
           justify the larger assignment. Where possible, the assignment
           will be made from an adjacent address block.


In IPv4 policy there are three major types of organizations that
addresses are delegated to.

   o ISP's receive allocations directly from ARIN or from other ISP's
   o End Users receive assignments from ISP's
   o "Large" and/or multihomed End Users may receive assignments directly
     from ARIN.

The third category is currently missing from IPv6 policy and
this is believed to be severely hindering deployment by those
organizations. In IPv6 policy-speak:

   o LIR's receive allocations directly from ARIN
   o End Sites receive assignments from LIR's

This policy proposes:

   o "Large" and/or multihomed End Sites receive assignments directly
     from ARIN.

This  policy applies to organizations with networks that are
large and/or complex enough to justify direct assignments.  Like their
IPv4 counterparts they do not make assignments to external
organizations. They instead assign space internally to their own
facilities. Similarly to IPv4 These internal assignments are not
submitted to ARIN via swip/rwhois.

A IPv6 network is considered eligible if it is multihomed.
For transition purposes an organization with an IPv4 assignment or
allocation from an RIR (or the legacy RIR) is automatically considered
elligible, regardless of whether they were considered an ISP or End
User under IPv4 policy.  It is expected that the IPv6 only (non
transition) requirements will be further refined as experience is

Since no /48's are assigned to external organizations, assignment size
is determined solely by the number of distinct physical locations to be
served (based on the 1 /48 per POP precedent for LIR's).  It is expected
that almost all assignments will fall between /44-/32. That assignment
range has been limited to nibble boundaries to simplify reverse dns.
The assignment thresholds for that range were determined using an HD
ratio of 0.94 in accordance with 2005-5.  A minimum assignment size of
/44 is proposed to allow for some growth and flexibility of use for the
smallest applicants.  /32's are not assigned by default because it would
be unnecessarilly wasteful for the vast majority of assignments.
