RE IPv6, there is some manual config.
I have each vlan/network assigned a /64. On my pi's they get an address in that /64 (different networks for eth0 and wlan0) but they do have a static assignment as well (should have included that earlier:
interface eth0 metric 300 static ip6_address=2403:XXXX:XXXX:XXX0::11/64 static ip6_routers=2403:XXXX:XXXX:XXX0::1 static ip_address=192.168.200.11/24 static routers=192.168.200.1
interface wlan0 metric 400 static ip6_address=2403:XXXX:XXXX:XXX3::11/64 static ip6_routers=2403:XXXX:XXXX:XXX3::1 static ip_address=192.168.209.11/24 static routers=192.168.209.1
