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 It’s over: IPv4 is obsolete and is provided in a legacy mode.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.
Even though email is supposedly “open”, and federated, is no longer is really the case. Big services like Gmail are suspicious of non-big-name servers, and often flag email coming from them as spam.
About a year ago I came across an article from a guy who’d been running his own email server since the 90s, and finally gave up. I couldn’t find that article in my quick search, but I did find this:

“I run my own email server. It’s no longer a good idea, because the anti-spam arms race makes delivery from small independent servers very difficult, even when you keep yourself off the block lists, so it’s a continuous struggle. Would switch, but I have too many domains/addresses”
Reminds me somewhat of Hurricane Katrina.
“The streets are on FIRE and they wont spread the news nationally . They wont send help. People call for emergency assistance and no one picks up the phone . #Sicily”
