Recommended Draft Policy ARIN-2014-13
Reduce All Minimum Allocation/Assignment Units to /24

Date: 20 May 2014

AC's assessment of conformance with the Principles of Internet Number
Resource Policy:

Draft Policy ARIN-2014-13: Reduce All Minimum Allocation/Assignment
Units to /24 - This proposal will lower all allocation(s) and
assignment(s) of IPv4 address in section 4.2 and 4.3 to a /24 minimum.
The policy would also remove section 4.9 as the allocation and
assignment sizes were now larger than 4.2 and 4.3. As noted in the
report it will also remove the maximum initial allocation that was used
with the examples in The changes to the NRPM are fair in that
they would treat all resource applicants equally. They are technically
sound and have received support from the community.

Problem Statement:

As we approach runout, more and more end users and smaller ISPs will be
unable to obtain space from their upstreams and will be seeking space
from ARIN. In order to meet these needs to the extent possible and to
make policy more fair to a broader range of the ARIN constituency, we
should reduce the minimum assignment and allocation units for IPv4 to
/24 across the board.

Policy statement:

Remove all references to minimum allocations /20 and /22 replacing them
with the term allocation or with /24 when referencing minimum size

Change the title of to "ISP Requirements" with revised text

All ISP organizations must satisfy the following requirements...thus
eliminating the entire Multi-homed section and subsections along with
other superfluous example text.

Delete the special case allocations/assignments for the Caribbean as
new /24 minimums are an improvement.

a. Timetable for implementation: Immediate b. A red line version has
been included

Full text version of changes for easy reference: Minimum allocation
In general, ARIN allocates /24 and larger IP address prefixes to ISPs.
If allocations smaller than /24 are needed, ISPs should request address
space from their upstream provider. ISP Requirements
All ISP organizations must satisfy the following requirements: Use of /24
The efficient utilization of an entire previously allocated /24 from
their upstream ISP. This allocation may have been provided by an ISPÂ’s
upstream provider(s), and does not have to be contiguous address space. Three months
Provide detailed information showing specifically how the requested
allocation will be utilized within three months. Renumber and return
ISPs receiving a new allocation may wish to renumber out of their
previously allocated space. In this case, an ISP must use the new
allocation to renumber out of that previously allocated block of
space and must return the space to its upstream provider. [section number retired]

4.3.2 Minimum assignment [section moved to 4.3.2]
The minimum block of IP address space assigned by ARIN to end-users
is a
/24. If assignments smaller than /24 are needed, end-users should
contact their upstream provider. [section number retired]

4.9 [section number retired]
