Hi Fernando,

To be clear, that would be a major change in ARIN policy. To date, all ARIN
policy operates under the presumption that following the initial justified
use for IP addresses, the resource holder is free to repurpose them in any
manner desired. The holder need only justify that use again upon requesting
additional resources from ARIN, and must then only demonstrate that his use
meets ARIN requirements, not that it was used as originally envisioned.

Also understand that ALL provision of Internet service which includes even
the ephemeral exclusive use of an IP address includes the lease of that
address. Try to draw a distinction between leasing just the address versus
providing service and you'll very quickly find yourself falling down the
rabbit hole. Do you have to provide IP transit with the lease? What if you
provide transit but the customer doesn't use it, he uses the transit he
buys from someone else? Is that good enough? What if the address lease is
24/7 but the transit is not (e.g. dialup)? What if the customer goes months
without using the transit? And do you mean to tell me that all a registrant
has to do to make his address lease kosher is offer the renter a 56k dialup
along with it?

Sure, we can set a requirement that you can't lease addresses without
providing transit. But that's such a ridiculously low bar to meet it's not
worth wasting ARIN staff resources to evaluate it. Unless we make it such a
high bar to meet that it actually impedes ordinary Internet business. Which
would be even worse.
