It's sitting just shy of 45%, based on what Google sees, and growing at a steady pace. The main issue is not technical, it's need. Right now, everything is accessible over IPv4, and probably over IPv6. There's no negative consequences from not having IPv4, it really needs initiatives like this one, and the US federal government one to drive things forwards (US federal agencies have to be single-stack IPv6 within a couple of years, which is forcing every government dealing vendor to get their act together on IPv6)
A couple months ago I got a new router and some stuff didn’t work until I turned off ipv6 (I don’t recall what, exactly)
I tried that solution early because when I first got Google Fiber the Amazon store website didn’t load, on any machine in our house, until I turned off ipv6. If stuff tries to route over ipv6, it doesn’t work, has been my entire experience with the protocol on the open internet (private networks seem Ok)
If you get 10/10 here everything should work.
Most likely your issue was a firewall rule on the IPv6 part, or a misconfigured DNS server (only returning A records)
My home connection fails because it’s disabled (of course).
Kicked my phone over to my T-Mobile cell connection. Finds that I have an ipv6 address, but dies on one of the first tests.
It’s 2024 and I have two major US ISPs available and neither will let me reliably use IPv6 unless I’m on a vpn and the addresses are all private ones that don’t (logically) route to the Internet.
