Based on the ARIN fee table of ISP classification: /20 is the max allocation size of a X-Small ISP
/22 is the max allocation size of a XX-Small End User. So there is a slight bias towards small ISPs, but they are in less of a position to leverage NAT.

Is there data behind that? If not, does it make sense to ask ARIN to supply data regarding sizes of transfers which have occurred in the past 12 - 18 months? -- Dani Roisman ________________________________ From: "Bill Buhler" <[email protected]<mailto:[email protected]<mailto:[email protected]%3cmailto:[email protected]>>> To: "owen" <[email protected]<mailto:[email protected]<mailto:[email protected]%3cmailto:[email protected]>>> Cc: [email protected]<mailto:[email protected]<mailto:[email protected]%3cmailto:[email protected]>> Sent: Monday, September 28, 2015 12:59:30 PM Subject: Re: [arin-ppml] Draft Policy ARIN-2015-9: Eliminating needs-based evaluation for Section 8.2, 8.3, and 8.4 transfers of IPv4 netblocks OK, how about this: Small end users and ISPs are allowed to obtain IPv4 address blocks without a needs test as long as the following criteria are met: a. The total size of their ARIN allocations at any time of the process does not exceed a /20 if a ISP or /22 for an end user. b. They cannot purchase IP address from the transfer market more than three total times to reach this size, including the initial operation. c. None of the addresses purchased can be transferred to any other entity for twenty-four months following the date of the last transfer. d. If the company ceases operations within the twenty-four month window the addresses are automatically transferred to the ARIN free pool. After that period of time regular transfer rights exist. e. All subsequent allocations / transfers require regular needs testing after the initial twenty-four month allocation window. f. Eligible entities for this policy consist of ISPs and End users who have a unique physical address in the ARIN region at the suite level. Meaning if two companies share the same suite they are not eligible to both have ARIN allocations. ------------------- I believe that meets all of your concerns. I would prefer companies get everything they think they will need in one operation, but I don?t want to have fear drive them into buying the max amount just in case. Best regards, Bill Buhler
