I am in favor of a brief reclamation hold. I am opposed to this
proposal, because the
duration is unreasonably long,  and by being unreasonably long it thwarts the
benefit of reclamation.

This is like baking a pie,  and deciding to let it sit out to cool for
90 days before eating,
so as to avoid the undesirable consequence of burning your mouth.
The problem is the wait is excessive, and when it finally lapses, you will find
it moldy and its usefulness expired  before anyone could eat it.

Early re-use of resources can have some undesirable consequences;
however,  not having sufficient resources can also have some
undesirable consequences.

I would favor a rule that IP addresses may be held after reclamation,
but before becoming eligible for reassignment at the discretion of ARIN staff,
no less  than 90 days,   and no  more  than  270 days.

With the understanding that long hold periods are for IP addresses
which are reclaimed after involuntary revokation, lack of use, hijacking, etc.

And short hold periods are to be used for voluntarily returned resources.
For example "return and renumber" deals.

If they are not used soon enough, a variety of undesirable outcomes may
result  (unavailability of IP addresses).

The concept of applying a hold here, is counter to the goal of network
in case of hijackings, the return to the proper holder should be as
soon as possible,
if there is one.

I would support a  18 month hold on reclaimed AS numbers and
an indefinite hold on reclaimed IPv6 space.

AS-numbers are not likely to be exhausted; so it makes sense to hold
them longer,
to avoid any possible confusion.

Unless there is a shortage, or ARIN needs more IPv6 resources,
the community should consider every properly obtained IPv6 allocation
permanent,  to keep things simple.

Reclamation efforts there (at this time) would just be
unnecessary/wasteful labor
