IPv4 Depletion

Mobile should have been IPv6 from the beginning. In China, it mostly is. If we could get all the handsets on IPv6, that would free up much address space. T-Mobile has been pushing IPv6, but they had problems with Skype and WhatsApp, which apparently don't talk IPv6 properly.

Is ipv4 depletion an issue for the big cloud providers (Amazon , Google, DigitalOcean, Rackspace)? How many ips do they have left?

There&#x27;s a secondary market that is surprisingly lacking in interest. I have a site that brokers large blocks of IPv4 to interested parties, and the most interest I&#x27;ve seen is for a &#x2F;21. We have a &#x2F;8 and can not come anywhere close to drumming up interest for it.<p><a href="http:&#x2F;&#x2F;ipv4hub.com" rel="nofollow">http:&#x2F;&#x2F;ipv4hub.com</a>

They really just need to set a date and say &quot;okay guys, on 1 March 2017 we&#x27;re all just going to drop IPv4 entirely, you have until then to get ready&quot;<p>Yes, there will be casualties.

IPv6 adoption is surprisingly slow. Shouldn&#x27;t it happen faster?

Seems like IoT would have much more to offer with IPv6. Currently you buy a &quot;internet enabled&quot; schlage deadbolt for your front door and it connects to cloud to enable remote lock&#x2F;unlock. If you could count on a visible IP address products&#x2F;services could skip such things.<p>Again it&#x27;s a chicken and egg problem, nobody does anything cool assuming IPv6 because few have it. Few have it, because you can&#x27;t do anything cool with it.

I feel lucky to have our little &#x2F;27 colo block.<p>We added IPv6 support to our firewall product earlier this year and it was a big deal - lots of schema and code changes to deal with 128 bit wide addresses and address math. I&#x27;d encourage any devs working on new products to bake it in from v1 if you can.

HP doesn&#x27;t need both those Class A blocks

What happens to the private sector end nodes? Do routers perform NAT from IPV4 to IPV6?
