For anyone wondering why they cant access their ipv6-addressed pi box from public WiFi networks: those public networks still use ipv4 and assign you only a lonk-local ipv6 address.

To go from 4 to 6, the public WiFi box will need to use a 4 to 6 "broker" and there are surprisingly few of these around and they're not usually free.

So basically, your home network and Pi is future-ready, but public infrastructure might need a moment...
