The main thing I don't like is type-ability. Even now I type in 192.168.1.14 to connect to my mates computer to play satisfactory. No way in heck am I trying in an ip6!
My biggest and possibly only problem preventing me from going IPV6-only is that Github doesn't support it, and there's just too much darn software I need to needs Github. (Yes, I know NAT64 exist - it's just extra complexity for something that is not even my problem in the first place).
Why not just expect your OS's DNS setup to actually just work?
Maybe use an OS or DNS stack that isn't terrible?
Incredible asking for a not-broken DNS and IP stack is just too far out there when it seems most of the closed source OS platforms seem to manage just fine.
Or let me guess, you've specifically configured it to not "leak" such useful information?
Router is all default except that I port-forwarded something. Funny enough, it sees the hostnames. I'm guessing it's some problem with both my computers, but no real need to fix this because I memorized the addrs already.
Admitting that ipv6 has some downsides, however minor they may seem to you, won't hurt your quest to render ipv4 obsolete.
In fact being less insufferable is how you win people to your causes, not by laughing at their genuine albeit minor issues.
