For those of us in the "NAT is bad"
(https://www.youtube.com/watch?v=v26BAlfWBm8) camp, the risk I
perceive with a purely capitalistic model is that many organizations will sell
their IPv4 address space to the highest bidder (who may hoard it) and even
more NAT will be deployed. While the effects of CGN are documented (i.e.
https://tools.ietf.org/html/rfc7021), I think that many network operators will
(choose to) ignore those (to the detriment of their end users) or capitalize on
that by charging extra to those who don't want to go through CGN. In
reaction, applications and services will be further modified to address CGN,
the opposite of my preferred approach towards end-to-end communication.

I'm not even a Smithian capitalist, and I see the first problem here:
Why doesn't it work?
Market stability will be reached according to every economic theory I've read,
regardless of whether the resources are finite or not. It may be that stability
means a gradually-increasing price for a while followed by rapid inflation, but
estimates I've heard posit that IPv6 deployment will be widespread by the
time the market price would otherwise skyrocket.

Really? How many universities and large organizations have /8s, /9s, and
/10s, that they would almost immediately start the process of monetizing?
It's "easy" (*cough*) - switch to NAT'd private addresses, switch to IPv6,
whatever. Heck, simple disaggregation of large blocks would release tons of
/16 and longer prefixes based on the usage patterns I've seen at most large
organizations. ISPs are not generally included in this, they tend to use what
they have. IBM, HP/Compaq/DEC, MIT, Princeton, Harvard, etc., etc.,
however, are the poster children for low usage. They just don't have a big
enough incentive to worry about it yet.
Also, see my previous posts for references to academic treatment of the fact
that hoarding *isn't a bad thing* in the free market. Of course, this isn't a
free market yet, so there's an argument to be made there...

The playing field is then level - all new entrants get to simply pay the going
rate, with no (perceived?) favouritism towards incumbents or large entrants.
This assumes there's a reasonable relationship between the price of a /16
and the price of a /24, of course. Smith's "invisible hand" should, in theory,
assure this...

Why should I have to disclose to a third party exactly what my plans are?
Even the IRS (or CRA, here) doesn't need that level of detail.
I'm sure the NSA knows exactly what my plans are, but if I have deep enough
pockets, I don't see why this resource - almost alone among all common
resources both natural and artificial - should be forbidden to me.
The only other example I can think of that is widely-known is New York (and
elsewhere) Taxicab licenses... and almost everyone except taxicab license
owners thinks that system is, shall we say, suboptimal.
All of the points above here are posited on the fact that the US is, at least
supposedly, a Smithian capitalist society that embraces the free market.
I happen to think capitalism is fundamentally broken, but at the same time
I'd rather let the market control what I can and can't do rather than a
handful of regulators who I *know* don't have my interests at heart. (Nor is
that their mandate, I don't mean they're behaving
maliciously!)
In essence, above is theory, below is practical.
Moving on to problems in the areas of policy, bias, and technical:

Does multihoming, per se, meet the (v4) needs test after the policy changes
in 2014? If yes, I can live with the situation. If no, then small entities
are still
getting screwed.
As a small-to-medium-sized enterprise, I probably NAT my entire company
behind one or two (possibly not even contiguous) IP addresses, with maybe
another half dozen publicly-visible servers. But if I want to be multi-homed, I
must first use >64 public IPs, and come up with a reason to use >128 public
IPs within a year. What if I just need those 6 or 7 IPs to be highly available?
Under the current NRPM, the only apparent way a small org can multi-home
(v4) is to get a reassignment from an ISP, at which point they're stuck with
that ISP pretty much forever, barring a painful and expensive renumbering
process (say, ~1000 incoming static VPN tunnels, not all of which are under
their direct control?).
(I also note that the multihoming justification for IPv6 direct assignment is
still there, even as the IPv4 justification is gone.)
This is the primary example today of how the NRPM is heavily biased
towards large organizations and SPs in the end-stages of IPv4 runout.
Meanwhile, if there were no needs test for /24s, and a healthy transfer
market, the organization would have the *choice* of paying for PI space or
choosing alternate workarounds with higher TCO (e.g. DNS-based load-
balancing, manual load-balancing, etc.). Right now, the small organization
that doesn't wish to become a sharecropper for their incumbent SP is - as far
as I can tell from reading the NRPM tonight - S.O.L.
The fact they can still get a direct IPv6 allocation is meaningless until IPv6
deployment reaches some reasonable density of penetration (>40%,
roughly), and I don't hear anyone here claiming that will happen until we
actually run out of IPv4 space, and SPs are no longer able to acquire v4 space
on demand. Small organizations already can't acquire
v4 space on demand - but they don't carry much weight with SPs.
Yes, the reasoning here is *partially* circular, because there are two related
problems converging to screw the small organization (which group includes
most of my customers, and in fact, most businesses in Canada).
Another way to view this, which has some relevancy to the problem
(mentioned earlier today) with separation between ARIN and NANOG, unlike
APNIC and RIPE which largely combine those functions, is that this wouldn't
be an issue if global routing tables carried prefixes longer than /24. The main
reason that's the case today - as far as I can tell
- is TCAM space on hardware routers, which directly translates into: Money.
[Rant about certain short-sighted & self-centered ISPs removed, didn't add
any value to the discussion, no matter how much it made me feel better.]
Right now we have this mixture of regulatory oversight and "market"
forces that indirectly control said regulatory oversight... this isn't IMHO a
healthy model, and any steps we can take to move either to a pure
regulatory function *or* a pure market-driven regime should improve the
situation. Given that ARIN is located in the U.S., a pure market-driven regime
seems like a better idea right now.
Regardless, small organizations are - right now - impossibly disadvantaged if
they want PI space for any reason, especially multi-homing.
If I've misread the NRPM v2014.4 (2014-Sep-17), feel free to correct my
interpretation... the only provision for low-usage multihoming of IPv4 I
could find is 4.2.3.6, which is commercially punitive, at least in my
region.
