From

	$ man dnsmasq

and looking for '--address' (and then for '--server'):

1. domain specifications in --address are the same as domain
   specifications in --server except for the addition of a '#' domain
   specification meaning "any domain" (rather than "any part of a
   domain" as you seemed to be assuming).

2. domain specifications in --server only allow domain names or the
   empty string '//' which means "unqualified domain names only".

So no, you can't have wildcards in --address domain names.

You do however have implicit "left side wildcards", as a domain spec of
"thisorthis.net" will match any domain /ending/ in "thisorthat.net", if
you can work with that.

The only way to get the behaviour you are looking for in dnsmasq would
be to modify the search_servers() function in src/forward.c -- without
of course introducing any bug or impeding efficiency especially under
high loads.
