Hi Owen,

8.3 today says "can demonstrate the need for such resources in the
amount which they can justify under current ARIN policies." There are
changes to that already in the pipeline, yes? Yet the policy -today-
(if the implementation matches the words) would seem to be that
section 4 requirements apply to 8.3 transfers as well.

This sort of process is my standing recommendation to my large end
user customers. At the /22 level even before the current /24 policy.

With large end users, one often finds that the central IT organization
is completely hopeless. It's routinely picked clean of anyone talented
enough to support a paying product, leaving it a bastion of
mediocrity. Even where not hopeless, central IT is rarely structured
in a way capable of facilitating a particular product group's need for
ARIN resources.

When a particular product team needs to stand up a multihomed network
for a new product, creating a distinct company to hold the network
resources allows them to approach ARIN with a clean slate. They're
judged only on their direct needs rather than be faced with the
impossible situation of addressing the larger company's activity,
activity over which they have no influence.

Policy-wise this works out more or less OK. Standing up the distinct
company is not an action taken lightly or cheaply. While oddly
constructed, it provides the same back pressure against careless
consumption that the policy's strictures are aimed at.

This probably isn't a "wonderful" result of current policies but I
haven't heard a credible alternative. ARIN and the RIRs are the major
gatekeepers to the BGP table and nobody has identified a practical way
to move money from the people who introduce routes to the people who
provide slots in the deployed routers.

You've heard the quote that "Democracy is the worst form of government
except for all the others." Well, same principle at work here.
