Pretty much! My ISP was founded by https://en.wikipedia.org/wiki/Rudy_Rucker and is somewhat cheap and delightful and happily routes me a good amount of IPv6, and every 48 hours or so it RAs me an entirely different range even though I still have validity on the lease for the old one and everything breaks, so I've had to turn IPv6 off entirely (I sent dumps of the relevant lease traffic to support, they said they'd look into it, and then the ticket auto closed after being inactive for two years). I spent a while trying to make things work with IPv6 but the combination of it being broken at my end and also there still being enough people I want to provide access to who don't have it means it just wasn't a good option.
One of my places uses Frontier FiOS (soon to become Verizon again). They have zero support for IPv6, and it isn't even on their roadmap.
I use a static HE (Hurricane Electric) IPv6 tunnel there, and it works great.
The only issue is that YouTube thinks the IPv6 block is commercial or an AI dev scraping their content, so I can't look at videos unless I'm logged in to YouTube.
I’m also on FiOS, and despite repeated statements to the effect I’d never get IPv6 on my (20 year) old ONT, I’ve got a nice little /56 block assigned on my kit via DHCPv6. Problem is that, as it’s a DHCP block, it changes, and Namecheap presently does not offer any sort of Dynamic DNS for IPv6 addresses.
Still, it let me tear down the HE IPv6 tunnel I was also running, since the sole reason I needed IPv6 was so our household game consoles could all play online without cursed firewall rules and IP reservations. I’m pretty chuffed with the present status quo, even if it’s far from perfect.
One other thing I’d note about OPs article (for folks considering it as a way to work around shitty ISP policies) is that once you have this up and running, you also have a perfect setup for a reverse proxy deployment for your public services. Just make sure you’re watching your bandwidth so you don’t get a surprise bill.
