[arin-ppml] Do people see a middle ground?

I'll try and make this one of the last questions.
Are there key functionalities that make a transitional technology
"acceptable" for most? Would the policy become more flexible if it were
written around this functionality, rather than trying to maintain a list
the technologies directly?

4.10 currently does nothing to define what is a "transitional
Arguably, addresses for dual-homed hosts could be called a "transitional
NAT64/IVI/etc. gateways serving a single residential customer could
arguably be called a
The reality is that if we allow such uses, there's no set-aside because
these "uses" are
essentially identical to the current "business as usual" (residential
get a single IPv4 address today, for example).
Staff has stated that 4.10 is too vague to implement effectively.
When 4.10 was adopted, I recall the discussion both on PPML and at the
expressly including an expectation that clarifying language for how to
use the /10 would
be generated as we got closer to need. Atlanta may well be the last
public policy meeting
prior to need. As such, I think it is important that we at least bring
something to the floor
for discussion there.

Can we get some examples of how 4.10 can be circumvented. That might
help the discussion about how to close any loopholes.

So far, proposal 116 does not establish a review panel and I remain
unconvinced that doing so is the correct approach vs. leaving it to
staff judgment guided by the BoT.
I'm open to any suggestions on a better way to limit abuse, but, it was
made obvious to by a number of people that 4.10 can be easily perverted
into pretty much business-as-usual by the creative leaving no IPv4
available for true cases of need in order to deploy IPv6. I would hate
us end up in that kind of dead-lock because we failed to address and
close a loophole in a policy that was passed with a general community
understanding of "This is a good placeholder, we'll make it more
when the time comes and we better understand the implications."
While you could well argue that we still don't understand the
significantly better than when 4.10 was enacted, I do not think it is
to argue that the time has not come. Atlanta may well be the last public
policy meeting prior to IANA runout. In fact, I will be very surprised
if it is
As such, I think it is very important to get something on the agenda for
with the possibility of becoming policy, even if we need to tweak it
in last call.
