A wildcard A record in your domain:

*.mydns.com. IN A 12.34.56.78

As for why it doesn't happen to names ending in .com, my guess is that you
have an entry for com.mydns.com, which is shadowing the wildcard in that
case.  This seems unlikely to me, so there's probably another explanation
that I can't think of offhand.
