I would argue that 80% aggregate is too high, but that is an entirely different discussion. Attaining high levels of utilization is very difficult for service providers. Customers often want, and properly justify, larger assignments. These requests are often difficult to fill when assignments are heavily fragmented for other customers only requiring /30's or /29's. This leaves us with a condition where some allocations are used more heavily than others depending on its specific purpose within the organization. My intent with this proposal was not to question the merits of the current policies surrounding utilization, but rather to fix what I deem an inefficiency in the current system which ends up being a huge drain on ARIN's and the member's time. To illustrate what I mean by this, each of my last few requests for resources have taken several days longer because ARIN employees are trying to figure out if the last assignment is used at 80% when all the space is aggregate is clearly over 90%.
