Doesn't matter. But in order for this trick to work:
- The things sending you queries must be able to receive your
replies. I believe you said that source addresses are spoofed,
so this may not be the case.
- The things sending you queries must be smart enough to follow
the NS referral in the response.
If I wanted to silently drop DNS queries based on the query name,
I might use FreeBSD's divert socket and a Perl script to examine
the queries. Not sure well that would scale though.
