If you are from The Netherlands I can recommend Freedom Internet [1]. A /29 (6 usable IPv4) costs 17 EUR/month (VAT equivalent included). That is less than 3 EUR per IPv4 a month.
I don't like this solution because it will cost me money and time to setup myself a modem that can handle properly ipv6 or switch to a more expensive provider.
Send the bill to end users is not what should be done.
All this ipv6 endeavour already cost me a lot of time learning and troubleshooting software, and sometimes realizing that some modems doesn't have a good ipv6 stack and the best solution is to turn it off.
Charging for IPv4 is mostly going to affect hosting providers. Until recently, AWS users were charged nothing for public IP so there was no incentive to conserve.
The price for IP for connections is already builtin to the price. Also, ISPs just use CGNAT to share IPs with multiple customers when they are short, It makes sense to charge more for static IP.
How long ago did you do try IPv6? These days it should just work. If your router doesn’t work, get a better router since it is broken.
By that chart, the IPv6 rollout will be basically complete by 2030. I suspect it will speed up near the end though as the first few services start to go V6 only.
I have a couple on my home network. Since I only have one public IPv4 address, port forwarding only allows me to expose one device on IPv4 on port 80. I could use a reverse proxy for those services, like I do for others, but as the only user who has reliable IPv6 on all my devices, there's no need.
What is confusing me is the Netherlands. We only have about 13% adoption. I'm on one of the largest ISPs KPN and get 10/10 on IPv6 tests. Is this because I use a custom router? I'd expect it to be a lot higher since apparently KPN supports IPv6.
* VodafoneZiggo has 40-45% of the home market, but also 25-30% of the business market and 20-25% of the mobile market [1]. They seem to offer IPv6 on their home and business connections, but not on their mobile connections [2, 3, 4].
* KPN (35-40% home/biz, 25-30% mobile): IPv6 for homes (except older modem types) and mobiles, but not by default for businesses [5, 6].
* Odido [ex T-Mobile] (30-35% mobile, 5-10% home/biz): no IPv6 across the board [7, 8].
Their data must just be out of date. It's been over a year that I've had IPv6 with Ziggo business and home. As you say, Vodafone mobile still only does IPv4 though.
The Ziggo shift would have made a huge impact on the national total.
