Michael,

The reference (6.5.8.1b) refers to the requirement for an IPv6
applicant to qualify for an IPv4 assignment under current policies.
The current IPv4 policy allows the assignment of a /22 to a multihomed
end-user who can immediately fill half of the /22. That's roughly 500
hosts.

This is why I call it a "back door" requirement.

They dealt with the phone number shortage by mandating technology
tweaks to the dialing process which opened up vastly more area codes.
Something to do with ten digit dialing and zeros in the second digit
of the area code; I don't remember the exact details. When we run out
of all 10 digits, they'll add a couple more and mandate another
dialing change.

In essence, they implemented exactly the kind of technology-tweak
based policy that you just criticized me for discussing on the ARIN
PPML list.

Despite years of foreknowledge that they could expect a problem, they
arrived in New Orleans a day late and a dollar short. If there's a
lesson to be learned, its this: don't do what FEMA did. Don't wait for
someone to call you. Don't wait for top-down. Get the components
staged in the field early so that when the s**t hits the fan the
resources are already there.

Bill Herrin
