<div class="moz-cite-prefix"><font size="4">1) " For cloud
providers your IPv4 blocks become your moat. ": It is
interesting that your closing statement summarizing the current
tactics of keeping customers captive and fending against
competition mirrors well with the "Towers of Babel" metaphor of
the ancient days mentioned by Christian a couple days' ago. That
is, the cyberspace "Towers" are controlled virtually by
multi-national businesses that extend far beyond conventional
geographical / political borders. It exceeds the comprehension
of most people. So, we must realize this situation and stop
promoting such.</font></div>

<pre class="moz-quote-pre" wrap="">True, but adding customers requires additional addresses at some point. IPv6 addresses are cheap compared to IPv4 addresses.

<pre class="moz-quote-pre" wrap=""> As an aside, all this demonstrates quite well one of the impediments to accelerated IPv6 adoption:
None of these costs apply to parties not growing or ones that are only growing withing their existing IPv4 allocation.
The status quo does not promote IPv6 adoption, which is obviously a problem since transitioning to IPv6-only requires all parties to be aboard.
I'll even add that there is a perverse incentive for ISPs and others to delay IPv6 adoption in certain segments. As there is a scarcity of IPv4, ISPs can charge a premium for access to IPv4 addresses, something you cannot do with IPv6. Furthermore as IPv4 blocks are acting like an appreciating asset, there is both an incentive to acquire more, regardless of need, and to hoard what you have, even if you don't need it. For cloud providers your IPv4 blocks become your moat.
