We have many service providers using virtualization with no problem at all; it is completely </div>
<div>compatible with ARIN's policies.</div>
<div>
<div><br>
</div>
To be clear, the policy manual discusses IP address _for customers_, and that is what</div>
<div>is described under NRPM 4.2 (allocations to ISPs). New requests are verified based on </div>
<div>documenting the assignment of the address space of the last block out to individual </div>
<div>customers. Those customers can be on dedicated servers, shared servers, virtual </div>
<div>servers, or anything else. </div>

virtualized hosts or infrastructure from contributing to a host count, why not require the requestor to provide some documentation of the validity of these virtualized hosts, perhaps through invoices showing that Customer A had an average of 30 servers and
a peak of 45 servers in the last month, Customer B had an average of 10 servers and a peak of 50 servers in the last month, etc, and then some aggregate data that shows many virtualized servers operated on average and at peak. It seems that in general the
community trusts ARIN staff to sniff out abuse – and if initially the requestors are required to show the last 3 or 6 or 9 months of invoices or virtualization data, that’s a lot better than the current practice of not being willing to count them at all. </span></div>

<div>Additional allocations are not based on equipment, but on utilization of the last IP address </div>
<div>block via assignments to customers. If ISP A gets to 80% because of great virtual hosting </div>
<div>sales, they can come get new addresses, regardless of the actual technology used. It is </div>
<div>true that if an ISP bought some equipment and used the addresses to turn it up, we'll consider </div>
<div>those IP addresses assigned as well, but primary driver is documented customer assignments.</div>
