Problem Description

I get a lot of XXX.1.168.192.in-addr.arpa type of dns look ups in the log listing, they litter the logs.

Proposed Solution

It would be nice to be able to just hide them, since they seem to be just internal network related lookups. So basically it would be nice if there is an option to hide internal ones, or only show external DNS lookups.

Thanks

This can be achieve using #594 or #1164 (and both)
