I will re-state all of this, to see if I have it right:

The OP wants example.com to return 1.2.3.4, but *.example.com to go up
the DNS tree and return the actual IP address.

Using -A/--address doesn't do this, it replies with 1.2.3.4 for
*.example.com as well as example.com, as documented (and presumably as
intended).

Setting example.com to be 1.2.3.4 in /etc/hosts or similar, and not
fiddling around with -A/--address should give the OP the required behaviour.

Is that an accurate summation?

        Cheers,
                Gary    B-)

Might try host-record=example.com,1.2.3.4
