I’m embarrassingly out of the loop. What happened with ipv6? Weren’t we supposed to run out of IP addresses the years ago? Will ipv6 still happen?

We've sort of run out of IPv4 addresses; you can't get new ones direct from ARIN in a timely fashion anymore. You can still get IPs from most of the other regional authorities though. You can also get IPv4 addresses from other people who aren't using them; there's still a lot of addresses that are assigned, but not BGP advertised, so there's some slack. However, IPv6 is happening. Primarily in two places: a) mobile ISPs; T-Mobile is big on IPv6, so is Jio in India. This tends to be related to new investments or wealthy countries. Existing networks work enough, so where there's not a lot of money, adding or upgrading CGNAT is small incremental cost, and enabling IPv6 is a project. OTOH, a big new network like Jio has to pick from building out IPv6 with a small amount of IPv4 or buying a bunch of IPv4 to build out a lot of IPv4 -- it makes sense to push hard on IPv6. b) big content sites. IPv6 networks currently don't have the same kind of junky middleboxes that IPv4 has --- serving as many customers as possible without junk in the way is a big deal. Where you don't see a lot of movement is residential ISPs in wealthy countries. They've generally got enough IPv4 for their customers, so they don't care that much about IPv6. However, Comcast has done a good job of rolling out, and AT&T and CenturyLink do have something.

Will ipv6 still happen? Yes. https://www.google.com/intl/en/ipv6/statistics.html https://www.google.com/intl/en/ipv6/statistics.html https://www.google.com/intl/en/ipv6/statistics.html#tab=per-country-ipv6-adoption https://www.google.com/intl/en/ipv6/statistics.html#tab=per-... I think we're clearly past the point of no return. How long it will take to achieve near 100% adoption I have no idea... but with ipv6 already at over 33% adoption in large countries like India and the US... yeah, it's gonna happen. All we really need is for Russia and China to get moving on adoption...

  China already did. For obvious reasons it just not shown on the Google statistics page.

    Good point. I totally blanked on that when looking at this.
