When changing my ISP I suddenly jumped in the world of IPv6 without any warning. Oh boy. I've been working in IT for 30 years, managed plenty of servers, host services at home, develop FOSS and whatnot but never got interested in IPv6. And I must say that this is a scary world. Some of my devices suddenly were getting their DNS settings from something else than the DHCP, I had to learn quickly about RA and other anagrams. I was super worried about the exposition of my services - something I completely controlled in IPv4. With this in mind, I think that IPv6 is too complicated. It does not have that sweet spot between "plug the green cable to the socket called ETH" and "I am going to try to squeeze some extra bits into the datagram".
