Illegal A record redirection

[Jason Brown]

If you are running apache as your webserver, then just create a named
virtual to catch all your legit DNS mapped websites and then create an IP
virtual to catch all other connections i.e. non legit DNS mapped websites,
you could even add a http redirect into the IP virtual to redirect it all to
somewhere else....

If you are running on a Unix box, you can blackhole the IP address that
is sending the packets to your machine.
