Excuse? Why?

I'm afraid some of you, including ARIN, are assuming, that IPv4
address space will last forever, if ARIN allocate the space
cautiously.

But, IPv4 address space will be used up, sooner or later certainly
before anonymous ftp become obsoleted and, perhaps, a lot sooner
than most of you expect and

Note that there is no requirement to preserve IPv4 address space forever
and the only requirement is to preserve IPv4 address space until we are
ready for IPv6.

However, the effort not to allocate enough IPv4 address space to
satisfy ISP requirements make name virtual hosts and NAT popular,
which, then, let people think IPv4 address space last forever,
which motivate ISPs delay the deployment of IPv6.

So, when we really use up the IPv4 address space, ISPs will not
be ready for IPv6.

The only reasonable solution for the problem, it seems to me,
is to assign a lot of IPv4 address space to good ISPs (good
means various things including that they are ready for IPv6) and
let all the ISPs realize the space will be used up soon.
