comment from the forum:
New ISPs in my country are IPv6-only because there is no new IPv4 space to be provided to them. They do have a over-shared IPv4 address by CGNAT but due to the oversharing, it is unstable and not rare to be offline. For these companies, the internet access is stable only in IPv6.
Thinking about the server-side, some cloud providers are making extra charges for IPv4 addresses (e.g.: Vultr.com) so most of the servers in my company are IPv6-only. Cloning github repositories is very cumbersome due to the lack of IPv6 support and this issue affects me and my team mates on a daily basis.
The math is simple: there are 4.88 billion internet users in the world but the IPv4 space only provides 4 billion addresses. It’s over: IPv4 is obsolete and is provided in a legacy mode. Current applications and services must be IPv6 enabled otherwise it should be seen as obsolete. For that matter, Github.com is an obsolete service because it relies on obsolete technology as IPv4.
Funny how different situations can be. I can’t get an IPv6 address unless I pay for insanely expensive business tiers.
I had a very small cheap ISP in France (Quantic Telecom) and they didn’t even monitor their network for ipv6 issues. I had to report problems myself every other week. They had less than 90% uptime in 2023, so I ended up getting a refund
Oof, imagine having to put a single 9 into your SLA. You would be laughed out of the room in a commercial setting.
Roasted
I wonder if they ever contacted github support, and what their answer was - rather than only posting on a public forum github doesn’t feel compelled to answer or make official responses to.
“IPv6 is not a feature; its absence is a bug”
- Someone on the Flathub repo, I think
I always use Github to check if my IPv4 DNS works lol (using
ping). So it’s definitely a feature /sWhen you’re relying on a bug as a feature
How hard is it to support IPv6? Does it require new hardware?
I used to study networking, albeit at a pretty beginner level. IPv6 has been around for nearly 30 years at this point, so I’d be surprised if the hardware github uses doesn’t support it. The impression I got was that it’s pretty easy to extend an IPv4 address space so there isn’t any rush to make a large scale move to IPv6 everywhere.
This is just sad.
Microsoft aren’t exactly big on implementing “the latest” stuff. Not at a keyboard currently but I’d be willing to bet GH doesn’t support TLS1.3 either.
Here: “yes it does support TLS1.3”
I shared the link partially because it’s a useful utility to check any public server TLS configs for vulnerabilities.

Microsoft implemented IPv6 over 20 years ago. I was seeing IPv6 settings in Windows 2000 and wondering when I’d get to use them. And I’m still waiting…
Does gitlab.com have it?

Neither do I.
I’ve talked to several network engineers over the years about IPv6, engineers that work as hands on with actual production infrastructure as you can get. And they all said that IPv6 would likely never be fully adopted.
But why ?
My understanding is it’s no longer that critical. The sky is no longer falling on IPv4
I am not a full network engineer so take my opinion with a grain of salt. From what I understand, NAT with IPv4 works really really well to mitigate IPv4 address exhaustion. Then there’s an issue with the amount of extra processing switches and routers need to do IPv6, we’re going from 32 bits to 128 bits which is a huge increase and for switches and routers that are handling packets as fast as technically possible with a low amount of resources typically, that’s a not insignificant hurdle.
It’s just easier to do IPv4 in every way, plus that’s what the world’s been using and is used to.
Also a reminder for me to add IPv6 support for my personal site. I think most cloud providers are able to offer dual ipv4/v6 support if you ask for it/configure it.

I also don’t have an IPv6 address. It’s my one complaint about my otherwise excellent ISP. They are offering /56 static IPv6 blocks for their multi-gigabit customers now, but not on the cheap plan I’m on. Not yet, at least 🤞.
Isn’t there a whole weird world of ipv6/V4 tunneling schemes that try to connect the two? https://en.m.wikipedia.org/wiki/IPv6_transition_mechanism Not sure if anyone supports these though
Yeah that’s probably how your phone gets everywhere, since mobile networks are usually IPv6
