Draft Policy ARIN-2017-9: Clarification of Initial Block Size for IPv4 
ISP Transfers

Problem Statement:

It was noted at the ARIN 40 Policy Experience Report, that there is an 
inconsistency in the initial block size for ISPs. Section 4.2.2 notes 
that the initial ISP block size should be /21 whereas the initial block 
size in 8.5.4 is noted as "minimum transfer size" which is effectively a 
/24. The intent of the new 8.5.4 was to match the previous policy. This 
policy is intended to clarify this issue. It was noted that ARIN staff 
current operational practice is to allow ISPs an initial /21 for Section 
8 transfers.

Policy statement:

Add the following to 8.5.4

ISP organizations without direct assignments or allocations from ARIN 
qualify for an initial allocation of up to a /21.

Comments:
