pfSense

Currently when pfSense is acting as a DNS server it can configure Domain Overrides. This is possible with dnsmasq and also with unbound.
Please make more than one IP address configurable. Currently for one domain you can exactly define one IP address. You want your DNS resolution to be as failsafe as possible. There are scenarios in which it's crucial that you can enter more than one redirection target.

Both unbound and dnsmasq are able to accept more than one IP. In unbound you can configure it like this:

forward-zone:
  name: "mypersonaldomain.com" 
  forward-addr: 192.168.12.4
  forward-addr: 192.168.12.6

In dnsmasq the server= directive is being used. For multiple targets it would look like this:

server=/mypersonaldomain.com/192.168.12.4
server=/mypersonaldomain.com/192.168.12.6

Of course also allow IPv6 addresses as a target.
