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 staff 
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 blocks.

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

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 the 
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 address 
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]
