GitHub is the main problem currently. Some software like composer does not work due to this.

For countries, if you meaning connecting to VPS, lot of countries have good IPv6 connectivity now. For me both ISPs I use have native v6. This will differ from person to person.

It is inconcievably stupid that github, run by a massive tech company like Microsoft, has not migrated to ipv6. They're single-handedly holding back adoption.

The massivest companies are the stupidest. Do what you can to avoid all Microsoft products.

My theory: Microsoft is extremely interested in tracking you via your IPv4.
