220.127.116.11. Initial allocation criteria
To qualify for an initial allocation of IPv6 address space, an
d) be an existing, known ISP in the ARIN region or have a plan for
making at least 200 /48 assignments to other organizations within five
There are several different ways to read that, but one can't interpret that
as merely requiring "200 sites".

No, it is not:
6.2.9. End site
An end site is defined as an end user (subscriber) who has a business
relationship with a service provider that involves:
1. that service provider assigning address space to the end user
2. that service provider providing transit service for the end user
to other sites
3. that service provider carrying the end user's traffic.
4. that service provider advertising an aggregate prefix route that
contains the end user's assignment

They'd have to prove that either they were a known ISP (which I doubt) or
that they planned to assign 200 /48s to other organizations (which I also
doubt). My reading of this is that ARIN allowed them to claim each physical
location was a separate "organization" because there was no other way to
fulfill their request, which was probably reasonable otherwise.
If this sort of game passes muster with ARIN, that means any company with at
least 200 locations (or at least a plan to have that many) or that pays a
few bucks to create 200 shell companies can get a LIR allocation. This is a
very slippery slope, and IMHO we need a true PI policy to put a stop to this
I've gotten a few private emails that list dozens of companies and other
govt orgs that have supposedly done exactly this; it's apparently the
best-known hole in IPv6 address policy. If end users are going to be
getting space, though, we should provide a more appropriate policy for them
(and assign from a dedicated block).

No, we assume they did. We're not privvy to what the ARIN staff saw or did
not see. Nor do I see why you assume that the IRS's computers will never
talk to the Internet; I agree it's irrelevant to the v6
allocation/assignment process, but I see no basis for your claim. Do IRS
auditors not surf the web on their lunch break like everyone else?

See my note above about shell companies and the slippery slope. I don't
know about your SMB, but mine could easily file some papers at the
courthouse Monday morning and qualify for an LIR allocation by that

There are some folks here who think every location within an end user org
should get its own /48, so that is potentially off by several bits, but
otherwise I agree with you.
