What will create a larger political storm is if we dramatically change
our policy to be lopsided towards one party or another.

If "big ISP" has the need for a /10 why shouldn't they be able to
acquire it after justification?

We have policy. That policy is followed by our members. If our members
have a need, they make a request. They request what they need. We
review their requests for allocations against our policy. Analysts
then determine that there is indeed a need. We've implemented checks
and balance and even officer certifications.

How do these ISP's or others expect to clean us out again?

Right, but again we're faced with one requester[1] fulfilling 100% of
their need and another fulfilling 1%. This is a situation very much
like the one with the recent global policy trying to return space to
the IANA from within the region[2].

I suggest that we instead change the minimum allocation unit as we
always have on a meeting to meeting basis and avoid creating a
specific policy with automatic triggers.

So, in order to [attempt to] avoid another five hundred post thread,
let me summarize:

1. Not in favor
2. Unfair to change mid-game
3. Creates an unfair condition where some get satisfied and others don't.
4. Could create an unfair advantage for competitors[3]
5. Invites BoT emergency power action since it has automatic triggers
that could fail on [unknown] existing conditions at any time.

I'd rather see the BoT invoke their emergency powers for something
that we "missed", not created.



1. Not all requests are from service providers. There are big
enterprises and infrastructure players who have large amounts of space
as well and are likely to have continued needs.

2. I'm still baffled as to why the lawyers agreed with me when I
stated the same thing re unfair and lopsided fulfillment with this
policy, but disagreed with me on another, similarly functioning
regional policy

3. IANAL, but seems to at least offer a whiff of anti-trust i.e.
restraint of free trade.
