What does this mean?

It means if your network is IPv6 native, you don't have to waste a very expensive IPv4 IP address, or proxy through one, to connect to it

And gone again (only IPv6 addresses there now are in the pages block). A short lived test? Or a bug/misconfiguration? GitHub has had no shortage of the latter unfortunately.

There are ranges in the "git" block, but it doesn't mean they're doing anything with it (until it's in the DNS or they publish specific IPs are safe to connect to it doesn't mean anything) This page is actually in the wayback machine (thank you!!!) and the same ranges were already listed in 2022 (not in 2021, didn't look for exact first occurence) http://web.archive.org/web/20220710073458/https://api.github...

I tried to gracefully port scan some likely IPs, based on their other conventions, and none were listening on 22. Quite a few listening on 443.
