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 It's over: IPv4 is obsolete and is provided in a legacy mode.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.

The IPv4 exhaustion is far more gnarly in developing countries. Something on the scale of hundreds of people sharing one IPv4 address.

If I want to get a public IPv4 address from my ISP, I have to spend extra. Some ISPs in my country simply don't give public IPv4 addresses anymore. They have completely exhausted their pool.

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.
