          <div>I haven't noticed a fear or a drop in the purchase or
            transfer of IPv4 due to the increase in cost. The movement
            was the opposite and many companies are not worrying about
            cost, they are increasingly buying IPv4, because that's what
            they know how to do, add more IPv4 blocks to their CGNAT.
            It's easier for them than investing in IPv6. I would say a
            suicidal move. Regarding Amazon's appropriation of large
            IPv4 blocks, I don't know what it will do, it's a gold mine
            and maybe the right thing would be to return the region.
            :-)) But I don't see any indication that it will do that.<br>

                  situation. Allow me to be brief. Our EzIP work started
                  as a curiosity about IPv4 address pool exhaustion. By
                  the time we came to something chewable, the Internet
                  community had decided to phase out IPv4. We were not
                  informed of the Working Group SunSet4, except allowed
                  to post semi-annual updates of our progress to IETF.
                  So, you would not have known the existence of such
                  IETF drafts unless you were specifically searching
                  with relevant keywords. What is interesting is that
                  recently, I began to hear certain opinions such as "<span>IPv6
                    is still seen as an option, rather than an urgent
                    necessity."</span> Also, there is a group of
                  Internet veterans who have been working on the "IPv4
                  Unicast Extensions Project" that tries to extend the
                  IPv4 in certain areas. One of them overlaps with EzIP.
                  You may want to have a look at it (see URL below). The
                  key questions at the moment would be; Is there

          <div>This draft of the block 240/4 release I will have to
            change all my class slides and let all my students know that
            something historic has changed! :-))<br>
            <br>
            Leaving the jokes behind, I imagine that these millions of
            IPv4 addresses that would be more available do not solve the
            problem of scarcity. Who cares about this? Or would it just
            be to accomplish a historic feat or correct a past mistake
            as well? I know that changes and mistakes happen. Imagine
            the work of changing software, firmware, acls, firewalls. Is
            it worth the effort ?<br>
            <br>
            About your question "The key questions at the moment would
            be; Is there anything that only IPv6 can do?"<br>
            <br>
            The question is very good and makes our mind work and heat
            up.<br>
            <br>
            I would start by answering as being the only protocol so far
            that can achieve an assignment to a large amount of
            equipment (IoT, 5G). In addition to the equipment and
            routers, they worked much better and faster in delivering
            packages. I would say that we have the opportunity to return
            and revive the concept of the early days of the Internet
            which is its end-to-end connection.<br>

                                                For example, the

                                                was IPv6 designed

                                                I came through the

                                                communications
                                                industries where such

                                                upgrading the equipment,
                                                except when one makes a

Buenos dias !

Compartilhando a entrevista sobre preocupações sobre a adoção do IPv6

<a href="https://www.theregister.com/2022/01/20/ipv4_nats_slow_ipv6_transition/" target="_blank" moz-do-not-send="true" class="moz-txt-link-freetext">https://www.theregister.com/2022/01/20/ipv4_nats_slow_ipv6_transition/</a>

Chamam a atenção os destaques:

"Carriers and Big Tech are happily continuing to use network address
translation (NAT) and IPv4 to protect their investments......."

"We are witnessing an industry that is no longer using technical
innovation, openness, and diversification as its primary means of
propulsion"

Saludos a todos !
