It’s a little bit unfamiliar, not the end of the world. It’s not complicated and not as nuanced as ipv4 networking. No dhcp necessary anymore on your local network, how good is that? No more trying to hardcode MTU, no strict/open/hairpin/fullcone/etc NAT issues because no NAT, no port forwarding, no fear of IP collisions, less overhead, freedom of many public addresses per interface - host each app on its own public IP address if you desire. Ipv4 over ipv6 is part of the spec so you would never lose ipv4 connectivity. I could go on

Roughly speaking, fd00::123 is the IPv6 equivalent of 192.168.0.123

Most of the time I do use hostnames, but it doesn’t matter what I use as a user if I have a list of addresses I have to look through in log files, or enter addresses for configuration or whatever. My brain works on IPv4. I’m sorry for ruining your day, but I assume, or at least hope, that you get paid for the work. I do not and I have more important and pressing things to do than learn IPv6 and reconfigure my whole network.
