People like you talking about IPv6 have the same vibe as someone bewildered by the fact that 99.9% of people can’t explain even the most basic equation of differential or integral calculus. That bewilderment is ignorance.
"Easy" is meant in that context. The people acting like the IPv4 version is easy.
So your second paragraph doesn't fit the situation at all.
"The shit about IPv6" is a mess of approaches that even the biggest fanboys can't agree on and are even less available on equipment used by people in prod.
IPv6 has failed wide adoption in 30 decades, calling it "easy" is outright denying the reality and shows the utter dumb obliviousness of people trying to push it and failing to realize where the issues are.
Not an issue in ipv4 because ARP isn't IPv4 so IP traffic shaping ignores it automatically.
Android doesn't support DHCPv6 so I can't tell it my preferred NTP server, and Android silently ignores your local DNS server if it is advertised with a IPv4 address and the Android device got a IPv6 address.
Without DHCPv6 then dynamic DNS is required for all servers. Even a 56 bit prefix is too much to remember, especially when it changes every week. So then you need to install and configure a dynamic DNS client on all servers in your network.
This is not even that unreasonable. Sadly, the number of IP devices in the world by now far exceeds the IPv4 address space, and other folks want to do something about that. They hope the world won't freeze but would sort of progress.
It’s not hard for people who get an appropriate education and put some effort into it. Your lack of education is not my ignorance.
