Hi Owen,

Can you explain how it would benefit the community for ARIN to use one
set of terminology in the NRPM and a different set of terminology in
its communication with registrants?

ARIN uses "ISP" in its software and operating practices, and
occasionally "LIR/ISP." If we want to zero in on a different term of
art, I think we have to expect the organization to harmonize on that
term. Consistency is just good communication practice. Zeroing in on a
term other than ISP will incur a cost in changed documents, modified
training and updated software.

On the other hand, adjustments to the NRPM definition of ISP that
don't particularly alter ARIN's practices, and harmonizing the NRPM on
that term, carry a negligible cost.

Regards,
Bill Herrin
