Hi Owen,

This raises a question that I find interesting. ARIN still allows IPv4
address assignments for individual registrant networks which are not
routed on the public Internet. The registrant has to supply some kind
of vaguely defined technical justification for it and I gather that's
not easy but it remains possible. Is it time to bring that era to a
close? Grandfather in the folks who've justified non-connected
assignments in the past but make no new ones regardless of
justification?

Let me reverse the question: in light of the situation on the ground
today, is there anything you would view as a reasonable justification
for an IPv4 allocation or assignment to a single entity which will not
be routed on the public Internet? What?

Regards,
Bill Herrin

Unfortunately, it's too late in the game to fix policies to favor protecting content networks (ie, eyeballs don't have to utilize NAT444 if they don't want to and can request address space until we are out, at which time they can convert, but the content providers do not have any new tools to deal with migration on their side). Trying to implement policy to deal with this unbalanced set of tools at this point would only cause a fast rush to ARIN by eyeball networks prior to policy ratification and defeat the purpose. As such, there will be a time that content providers cannot offer IPv4, and their competitors (especially eyeball networks who sideline content) will have IPv4. We will have effectively killed the little guy.
