I also configured the local network resolution, and seems very slow between each ping. It seems to resolve the full IPv6 address :
ping -6 pi4.home
PING pi4.home(00000000000000000000000000008e66.ipv6.my.isp.com (0000:0000:0000:0000:0000:0000:0000:8e66)) 56 data bytes

When disabling Conditional forwarding and adding Local DNS CNAME entries :
It resolves the local IPv6 address, but it's very slow between each request
