Perhaps you did not recognize three characteristics of the
EzIP scheme in this respect:<br>
</font>
<p><font size="4"> A. It is an incremental enhancement
(more addresses become usable). It does not require
end-user upgrade. So, it does not interfere existing
operations, </font></p>
<p><font size="4"> B. It is localized within a RAN
(Regional Area Network), or a partial branch of such,
and generally deploys down-stream. So, it should be
within one Network Operator's sole jurisdiction,</font></p>
<font size="4"> C. It is a "generic" type of software
upgrade. That is, all equipment from manufacturers using
the same root software block are likely making the same
code change.</font><font size="4"> </font><br>
<p><font size="4"> As such, the software update for EzIP
operation may be done as part of </font><font size="4"><font size="4">periodical debugging type of down-loads, not
extra burden on operator's staff.</font> Then, the
added capability can be idle in the updated equipment
until down stream facility is ready to take advantage of
the expanded capability. From my knowledge of equipment
maintenance, this is no big deal. Although this is not
without efforts, it would be finite compared to the IPv6
deployment that requires wide spread compatibility
through the Internet (cooperation of both ends of a
link), before the roll-out of the capability is
feasible. </font></p>
<br>

This part of the proposal doesn't have in mind the operations of a network:
</pre>
<blockquote type="cite">
<pre> A. Disable the program codes in current routers that have been
</pre>
</blockquote>
<pre>disabling the use of the 240/4 NetBlock. The cost of this software
engineering should be minimal.
Yes, let's say that the cost for Vendor A could be minimal: they will
remove some lines in the code for version X.Y and release version X.Y-EzIP
without bugs triggered by removing those lines. Then, we, the operators,
would have to plan the upgrade of all of our routers, spend days
programming the upgrade, spend nights in maintenance windows, maybe pay for
remote hands, etc., just to extend for a few more days the inevitable agony
of IPv4.
Thus, the cost of the so-called EzIP is not minimal.
