Fwd: NXDOMAIN Analysis

[Silva Carlos]

 Hello everybody

I am newbie to BIND DNS.

I would like your help to understand a little more about the problem below,
please:

****Problem:* Sometimes my DNS reports too many NXDOMAIN responses.

****Question 1*: Is there any way to identify the site/domain that is being
consulted and consequently generating NXDOMAIN?

****Question 2:* Is there any way to identify the DNS client that is
querying this non-existent website/domain?

 I use DNSTOP, but it doesn't have a lot of information.

Many thanks to whoever helps me.
