Hello Ran,

In regard to mention of ARIN in this discussion,
I offer two points of clarification:

1. ARIN does not have policies in place that require 
organizations to use NAT when providing services to 
customers.  ARIN staff are under strict instruction 
to not even suggest the use of NAT to organizations 
who request IP address space from ARIN.

2. ARIN does not have policies in place that relate to 
charging schemes for service providers.  ARIN does not 
in any way make recommendations to service providers 
regarding how they charge customers for service, or the 
use of IP address space.

Please let me know if I may provide any further
information on this subject.

Best Regards,

Richard Jimmerson
Director of Operations
American Registry for Internet Numbers (ARIN)
