> I'd be willing to place a wager that there will be a $100mm company that is only IPv6 by 2030.

And at 60 percent usage, it will probably be India[1]

The trend on the "IPv6 Adoption" tab is fascinating. It looks like the inverse of the usual "high traffic during the week, low traffic during the weekend" pattern that I'm used to seeing in traffic graphs.

I wonder why? Is IPv6 adoption significantly higher for residential internet connections vs. corporate networks?

I mean yes, people who don't know what an IP is use whatever their ISP gives them, and ISPs have mostly rolled out v6 by now (albeit imperfectly). Businesses actually manage their networks actively, and they use what they know, which is almost always v4.

Mobile Network operators have been quite forerunning with regards to ipv6. That is primarily the driver for ipv6- iOS forcing apps to have an ipv6 backend was a huge driver too for services.

That‘s never been a requirement. What Apple does require is that apps correctly work over an IPv6-only network that uses NAT64/DNS64. Which means not hardcoding any IPv4 addresses and generally not expecting domains to exclusively return IPv4 addresses.

Corporate customers are very slow to transition to IPv6. Most of them aren't feeling pressure on the IPv4 space the way ISPs are and corporate security appliances are notoriously slow to adopt IPv6.

Yes, residential users have a lot more IPv6, a lot more of almost anything modern (but somewhat regardless of whether it's necessarily better).

Even if IPv6 is used internally, a lot of enterprise environments have outbound proxies which will use IPv4 by default. For example HP may have a /8, but all outbound is forced through a small number of PoPs with very enterprisey http proxies.
