<div class="moz-cite-prefix"><font size="4">0) As the saying
goes, there is more than one way to skin a cat. We do not need
to address a request by literally following the thought trend.
In troubleshooting, engineers are taught to look for the
Root-Cause which more than often turns out to be something else
originally thought. In this case, the "Any idea" hints that
requester is open-minded for possible alternatives other than
stated on the surface. <br>

<div class="moz-cite-prefix"><font size="4">1) When reviewing a
problem, we need to go one or more steps toward the source or
the origin to look for the solution. Since the predominant
operation model is CDN supported by CG-NAT, the primary reason
to look for a publicly routable IPv4 address is to create
another CG-NAT cluster. On the other hand, if there is a way to
expand the capacity of the existing CG-NAT cluster, the need for
additional publicly routable IPv4 address is reduced.<br>

240/4 has 256M addresses while 100.64/10 has only 4M, a
current CG-NAT cluster can be expanded 64 fold once the
240/4 is used. Looking from another angle, an IAP will
then be able to expand the subscriber set 64 fold with
still the original one publicly routable IPv4 address.</span></p>

would expect they want actual public IPv4 address blocks
