For the purposes of the RIRs and for any ISP assigning or allocating address space downstream, 'utilization' refers to an appropriate assignment made. If I have properly assigned 80% of an address block to my customers, I am 80% 'utilized' for the purposes of the RIRs. It is entirely irrelevant how much address space is actually being used, on an IP x IP basis by downstreams. If the assignments were justified per RFC2050, and the upstream has assigned 80% or more of its available address space, then it requires another block. > To an end user, it means active hosts.

ARIN requires ISPs to follow RFC2050's guidelines for *initial* assignments to end-users. End-users must demonstrate a need for 25% of the requested assignment immediately, and a need for 50% of the requested assignment within one year. For *additional* address assignments from an ISP, an end-user should demonstrate that they have utilized (in this case, meaning active utilization in a 'live' sense) 80% of the initial assignment. The difference is an important one. 25-50 is for *initial*, 80 is for *additional*. > This is even more confusing when the customer is both an end user and > a downstream ISP themselves.

The RIRs use the words "ISP" and "end-user" slightly differently than other folks. Any organization which does not assign their address space further downstream is considered an "end-user". It doesn't matter what their business activities are (indeed, they may be a service provider). For the purposes of this discussion, for the purposes of the RIRs, they are an end-user. /david
