Yes, this is what I need for v6 only. However, as you can see from my earlier example, A query failed as well:
query[A] www.xxxx.xx from 192.168.x.x
config www.xxxx.xx is NODATA-IPv4
At the moment I'm getting the desired result with unbound with the magic python script [running on pfSense].
Will be great to have something similar on Pi-hole directly. Please don't suggest to install unbound
