ARIN-prop-244: Clarification of Initial Block Size for IPv4 ISP Transfers

Date: 10/07/2017

Proposal Originator: Andrew Dul

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.
