[dns-operations] Interesting messages in our logs

[Lyle Giese]

Interesting error messages.  Someone was running a host name scan against a domain hosted here and it looks like they were doing it via Google DNS.

My question is related to Bind 9.9.5-P1, which we are running here.  What is the response from NAMED at this point?  Does it just ignore the request or does it send back some kind of error messages related to the requestor?
