This policy attempts to address these issues, by raising the minimum
size to a /24 and limits total amount an organization can receive to
a /21. It also removes the requirement for return and renumber, since
that was primarily added to allow organizations to obtain larger
blocks if that was necessary. The policy also clarifies the
utilization requirements by placing them directly in this section
rather than a reference to the utilization requirements of end users.
Policy Statement:
Replace current 4.10 with the following updated section
4.10 Dedicated IPv4 block to facilitate IPv6 Deployment
ARIN shall allocate a contiguous /10 from its last /8 IPv4 allocation
from IANA. This IPv4 block will be set aside and dedicated to
facilitate IPv6 deployment. Allocations and assignments from this
block must be justified by immediate IPv6 deployment requirements.
Examples of such needs include: IPv4 addresses for key dual stack DNS
servers, and NAT-PT or NAT464 translators. ARIN staff will use their
discretion when evaluating justifications.
This block will be subject to a minimum and maximum size allocation
of /24. ARIN should use sparse allocation when possible within that
/10 block.
This contradicts the statement above that the maximum allocation or
assignment is a /21, not a /24. Or is it intended that the initial
allocation or assignment is always a /24, but the recipient can later
ask for more, up to a /21, with appropriate justification?
Or is it worded that way so that if an applicant comes back for a
second (or subsequent) allocation/assignment under this section (for a
second discrete network?) they may receive no more than a /21 in total?
Also, if the allocation or assignment is a /24, no more and no less,
what is the point of the 2nd sentence that ARIN should use sparse
allocation? Is it so applicants taking a second dip will, if
possible, get a contiguous /24 each time?
The original intent of this rewrite is that the initial assignment or
allocation will always be a /24. Any additional assignments will also
be a /24. An organization could come back every 6 months to get more
addresses up to a /21.

And the "sparse allocation" provision is to accommodate that? Okay, got
ya. My worry was the intent was to reduce the /21 max to /24, in which
case the "spares allocation" provision no longer made sense.
