    7. Policy statement:
                 NRPM and ISP private reassignment
                 ISP has the option to register a reassignment as 
private.  A private reassignment is not visible on the public whois 
database.  Private reassignment is used in calculation of ISP 
utilization.  By register a reassignment as private, the ISP takes 
responsibility as POC by means of the direct allocation (parent of the 
reassigned address block) from ARIN that is publically registered in the 
whois database.

    8. Rationale:
                 Some ISP's customers wish to keep their reassignment 
private.  This can be for security reasons.  It can also be that the 
customer does not have the staff or know-how to manage their network.  
They in term outsource the management of their network to the upstream 
ISP.  By not having their reassignemnt record showing in public, the 
whois record of the parent ISP block is a truer representation of the 
reality.  It make shte whois database more accurate and cleaner.
    9. Timetable for implementation: immediate
