People have been asking for IPv6 Support on GitHub since years (probably a decade by now)
... and someone even got so annoyed that they decided to setup a dedicated website for checking this: https://isgithubipv6.live/

But new IPv4 allocations have run out. I've seen ISPs that won the lottery in the 90s/2000s (when the various agencies controlling IP allocations just tossed them around like they were nothing) selling large blocks for big money.
Many ISPs offer only CGNAT, require signing up to the higher speed/more expensive packages to get a real IP, or charge extra on top of the standard package for one. I fully expect this trend to continue.
The non-move to IPv6 is laziness, incompetence, or the sheer fact they can monetize the finite resource of IPv4 addresses and pass the costs onto the consumer. I wonder which it is.
Oooh is that why ipv6 adoption is so regional ( Based on https://www.google.com/intl/en/ipv6/statistics.html ) . Like france ,germany or india having more than 70 % while italy or poland hanging below 20% ? Also judging from this site it seems like ipv6 is actually getting adopted at quite the rapid pace. Even if some regions are faring way worse than the others.
Apparently it's still cheaper to buy IPV4 blocks than to upgrade all the equipment and IT staff to use 6.
Any (enterprise grade) equipment not capable of 6 that is still in use is a ticking time bomb.
I mean, at least over here, a white IP has been a paid service for as long as I can remember. Absolute majority of people don't need a static IP, which is why we haven't had internet "breaking" because of IPv4 running out.
But this is another interesting thing. Dynamic IP addresses made sense, when we were dialling up for internet, and the internet wasn't the utility it is now.
Back then we'd dial up for a few hours in the evening or weekend. Businesses that didn't have a permanent presence would connect in the day to send/receive emails etc. So, you could have 500 IP addresses to around 1500 users and re-use them successfully.
But now, what is the real point in a dynamic IP? Everyone has a router switched on 24/7 sitting on an IP. What is the real difference, in cost in giving a static IP over a dynamic one? Sure, CGNAT saved them IP addresses. But, with always on dynamic just doesn't make sense. Except, that you can charge for a static IP. The traffic added by the few people that want to run services is usually running against the tide of their normal traffic. So, that shouldn't really be an extra cost to them either.
If everyone that ran a website did the extra work (which is miniscule) to also operate on IPv6, and every ISP did the (admittedly more) work to provide IPv6 prefixes and ensure their supplied routers were configured for it, and that they had instructions to configure it on third party routers, IPv4 would become the minority pretty soon. It seems like it's just commercial opportunity that's holding us back now.
From what I understand about the providers, they really don't like it when you're generating outbound traffic. Sure it's advertised to be symmetrical, but the actual hardware they place here can get bogged down if you start hosting a popular site (or seeding too much).
And of course, if they can charge you for a static IP then defaulting to dynamic is imperative, isn't it? Pretty sure they'd try that with IPv6 too just to keep the income stream.
Regardless, the actual issue with IPv6 around here seems to be that the providers either don't know how to or don't care to implement it properly. Sure I can tick on "IPv6" in my router, but that doesn't mean I have an unbroken chain or routing hardware that supports it connecting me to the great internet.
I've mentioned it elsewhere. Some ISPs here in the UK have a dynamic IPv6 prefix. Want a static one? Sure, pay up.
I suppose to an extent this kind of thing is akin to low cost airlines. Sure you can "technically" get a flight for €15. But once you've made it even remotely bearable you'll be paying around the cost of a full service airline. But, it does make it very hard to have a website doing a proper price comparison.
I suspect it's the same here. I pay a bit more than most ISPs. But for that, I get decent in country support, fixed IPv6 prefix and static IP (I actually have a legacy IP block, but you don't get those included in the base price any more). Whereas plenty of other providers charge less, but will charge you for anything beyond the most basic of connections. It means my ISP always appears at the expensive end of price comparisons.
Yeah, I just checked, getting a static IPv6 here in Russia from my ISP costs ~.4 eur per month. IPv4 is ~1 eur, so you get a discount if you go for v6! Oh and despite my ISP saying they support v6, connection I got doesn't have it at all. Probably whatever hardware they got in my house doesn't know what it is.
a combination of all of these, most likely
