Since this was the first message to bring up the 80% vrs 25%/50% rule
I'll use it as a base for the reply. I asked hostmaster at arin.net which
interpretation they use day to day, and if it had always been that way.
My original questions and the hostmaster reply:
] > If an ISP receives an allocation from ARIN (say, a /16), and then
] > reassigns a subset of that space to a "end user" customer (say, a
] > /24), what usage criteria do they need to follow?
] > In particular:
] > A) The customer must show 80% utilization of their /24.
] > B) The customer must show 25% immediately, 50% within one year.
] B) is the correct answer
] > Also, regardless of the answer to that question, has ARIN always

] ARIN has always applied this principle, as per RFC2050 section 3.1
Based on this response, I suggest updating the text of section 3 under
http://www.arin.net/policy/ipv4.html#additional to read as follows
(lines changed indicated with a plus):
| 3. Require your downstream customers to adhere to the following criteria:
+ * When the customer is a network operator:
| * 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. Note: To
| maintain the privacy of residential customers, the person's street
| address and phone number will not be provided.
| * Customers must follow ARIN guidelines for ISPs
+ * When the customer is an end-user network:
+ * Customers should be documented to meet the end-user assignment
+ criteria set forth in the next section.
| * Web host customers should report usage data in a form similar to
| the chart shown above
I realize it's being a bit verbose, but it will eliminate any
confusion about which criteria to apply, which given my quick google
results earlier and my own personal experience is quite rampant.
