Auditing. Not all information gathering is used for bad purposes :-)

For example, I've developed an DNS auditing system to check the
state of health of our servers, the ones which we (were) delegated
(delegating) to... Warnings kept popping up for weeks after the
transfers of domain from a remote server to us or from us to another
remote server. If you don't check and complain your DNS-network is
going to be a mess, mail won't be transfered anymore, hosts will
resolve wrong and all kind of things based on hostname-authorisations
will go bad.
