Sure. I have no doubt that most ISPs record what a /32 assignment is 
assigned to. The problem, and the burden comes in the fact that the 
records kept for such things do not reflect what ARIN may ask for.

Example: details of each piece of equipment that the ISP assigns an IP 
to. Some ISPs may have easily queried inventory systems. I suspect most 
small ISPs do not, and some large ones may not be able to easily query 
the information.

Customer assignments may go across multiple databases or spreadsheets, 
depending on how the ISP setup. I've seen spreadsheets that assign an IP 
to an interface, then spreadsheets that assign an ATM PVC to a phone 
number, then a billing system that attaches the phone number to a 
customer name. In addition, there may be a separate database that 
contains a username/customer name/IP assignment information, but the IP 
information is just an added note. ie, it's easier referenced one 
direction than it it the other. Given a certain user, you can lookup 
what IP they use, but given an IP, more work is required to find the 
user; much less provide a report for ARIN.
