There is an ICANN presentation about IPv6 deployment in

<div>Yes, Alain Durand of ICANN was saying this to everyone
who cared to listen in Dakar and even said to me "You are
lying" after I responded to a fellow that "IPv6 is the
answer to IPv4 exhaustion"</div>

<div>I would really much like to find that presentation where
he makes that argument. I've been too shocked to respond
because when you someone brazenly says something like that
it means one of two things</div>

I think it was fundamentally similar to
<a class="moz-txt-link-freetext" href="https://www.slideshare.net/apnic/ipv6-deployment-a-global-perspective">https://www.slideshare.net/apnic/ipv6-deployment-a-global-perspective</a><br>
<br>
Slide 27 says:<br>
<br>
* Until IPv6 reached [sic] XX penetration in YY countries, IPv4 will
remain relevant<br>
* (XX and YY may vary depending on business views)<br>
* Until then, IPv6 is NOT a general replacement for IPv4.<br>
* The IPv4 address market might be in here [sic] for the long run.<br>
<br>
The fundamental problems with these points:<br>
1. Nobody has ever said that IPv4 will be irrelevant before some
debatable level of penetration. That's attacking a straw man.<br>
2. It ignores local realities. For many networks, YY countries
doesn't matter, only the sites (or networks or hosts etc.) their
users hit. If none of your users accesses smaller web sites in
remote countries, then you probably are willing to take the risk
that someone might eventually.<br>
3. Except that address translation exists, so you don't have to take
that risk. IPv6 can be a general replacement for IPv4 *in a given
network*, if combined with translation to IPv4.<br>
4. It's strange that he mentions the address market out of the blue.
<br>
<br>
My guess is that content networks, including cloud and CDNs, will
keep buying IPv4 addresses for some years. Some, like Facebook and
LinkedIn, are deploying IPv6 inside their networks and providing
translation at the edge. Others may start doing that.<br>
Access networks, such as ISPs, corporate networks, and universities,
will do what mobile providers have always done: some combination of
NAT64 (including 464xlat) and NAT44.<br>

Alain's statements seem to be inconsistent with ICANN's statements
and goals around IPv6:<br>

<br>
I have copied a media contact for ICANN, hoping we can get
clarification on ICANN's position, represented to a conference in
Asia in the slides above, and in Africa in this conversation.<br>
Here is the conversation thread for this Afrinic list:<br>
