Thanks for this contribution! I've added it in r36867, with slight
modification:
* Instead of disabling the record type, we check each answer against the
wildcard address and only show it if they differ.
* Removed the change to SRV record enumeration, since we want these to be
shown simply because they exist as names for SRV records, even if they only
resolve to the wildcard address.
* Added a couple minor, unrelated refactorings that made the existing code
a little clearer.
Very useful! nmap.org uses wildcard records, so you can test (lightly) on
that.

Hi!
The dns-brute script will happily list all configured hosts if a domain
uses a wildcard record.
This PR adds detection for A and AAAA wildcards, and disables the type of
record it thinks is a wildcard. I've added script arg dns-brute.force to
override this.
All and any feedback is welcome. If I can improve this somehow (some
built-in random string generation maybe?) please let me know!
Cheers
