4.2.3.7.5. Accounting for additional utilization

The following format should be used to provide the required information for utilization of blocks smaller than /29 and for describing internal networks when either SWIP or RWhois server is not used:
City Which IP Addresses Assigned No. of Ports No. of Dial-up Clients
City Which IP Addresses Assigned No. of Internal Machines Purpose
Which IP Addresses Assigned List URLs for Websites

basically in short if you have more than 5 ips and your host gets challenged by arin.. which they will.. because we have been challenged by arin when we got our latest allocation they will ask for proof of customer information and their allocation details and how they are used.

I can't wait to see what some hosts start doing when this happens.
