ARIN does review requests for IP address space from end-users who can justify the minimum assignment size of a /20, as described at http://www.arin.net/regserv/ip-assignment.html It is true that end-user organizations who request additional IP address space directly form ARIN must demonstrate 80 percent of their prior assignment has been efficiently utilized before their new request may be considered. It is also true this is not stated at the above referenced URL. It is stated at a different URL where ISP guidelines for issuing additional IP address space to customers is described (more about this below). A discussion about adding this language to http://www.arin.net/regserv/ip-assignment.html will take place on ARIN's public policy mailing list ([email protected]). ARIN's policy mailing lists are open to everyone. Subscription information and archives can be found at http://www.arin.net/members/mailing.htm When it comes to ISPs who assign IP address space to their end-user customers, it is expected the assignment size will be determined based on the customer's 25 percent immediate and 50 percent one-year needs, as described in RFC 2050. It is also stated at http://www.arin.net/regserv/addipspace.html that ISPs need to adhere to the following when considering requests for additional IP address from their customers: "Reassignment information for prior allocations must show that each customer meets the 80% utilization criteria and must be available via SWIP/RWHOIS prior to your issuing them additional space."
