I'll second the comment that it's great to get these assessments in
advance of the meeting.  Thanks!

I wanted to take a moment to respond to the staff comments on this
one.  Comments inline.

Do spammers take the time to become multihomed and then apply for IP
space?  If they do, I'm sure they can find a way to qualify under the
existing policy for a /22.  I'm not sure I understand the actual risk
here.  It seems to me that this could already be a problem, actually.
Perhaps a process to identify or report spammers would help this
problem, but I'm not convinced that spammers actually try to get valid
IP space from RIRs.  Do we (staff and or community) have any data on
this possibility?

This is true.  It is likely that a small multi-homed enterprise would apply
for space under this policy rather than applying for space via an ISP.

I respectfully disagree with the first sentence entirely.  Existing
policy is heavily biased towards ISPs, and is rather unfair for smaller
entities that have a critical business need to be multi-homed, but wish
to avoid being semi-permanently attached to a single ISP due to the
need for address space.  Indeed, the current lack of fairness is part of
the desire to change the policy.

On the second point - I agree that this could be an issue.  I suspect
it could be an issue now...there's nothing to stop an ISP from applying
for a /22 as an end user, outside of the risk of getting caught by staff.

Existing policy, as written, refers to section 4.3.3.  That doesn't
change with the proposed policy.  ISPs can feel free to reassign a PA
/24 via whatever policy they choose, but direct (PI) assignments should
still be under the guidelines listed in 4.3.3, regardless of the
minimum assignment size.  There is explicitly no change in that.

My intention for this issue is that this is handled in the same way
that multiple /22 requests are handled now.  Is the request justified?
There's no change in how this would be handled, outside of the
differences in minimum assignement size.

I'm happy to concede this point, and change the policy appropriately.
I'd like more (as in any) community input on this point.  To some
extent, the IPv4 micro-allocation section is irrelevant if this policy
is approved.  On the other hand, it may be useful to explicitly call
out the allocation policy for critical infrastructure.  What that
infrastructure is defined to be is an interesting question, but beyond
the scope of the current proposal.  More opinions solicted!

Thanks again for the opportunity to get some of this discussed in
advance of the meeting!
