Returning values for unapproved queries

[cool]

Hello,

	At our site we get quite a few unapproved DNS queries. It seems
some people like to set their DNS to be our servers. I was wondering if there
is a way to return a certain response when this happens. For example:

Nov 26 11:55:53 foo named[89]: unapproved query from
[x.x.x.x].1354 for "www.foobar.com"

I would like to return to x.x.x.x our home page instead :). This way they
will know something is wrong with their internet setup and will be forced
to fix it.

Thanks for any help.

Viraj.
