It's not "NetWorker weirdness" - NetWorker relies heavily on DNS to validate 
clients -

Mminfo is used to query the media database, if you have a bunch of old media 
that is still in the media database that has savesets from decommissioned 
servers then mminfo will try and  resolve those host names, and throw a warning 
if it is unable - the easiest way to speed things up and to stop these messages 
is to put entries in your local host file - or you could remove the referenced 
to the guests from the media database, or remove the old media from the media 
database or fix up DNS so that it can resolve the host names

BUT  ... you have to be mindful that you are probably retaining these backups 
for a reason, and these is probably a policy that says thou shall keep backups 
of decommissioned servers for x years ... and bodging up false records in your 
local hosts file, or  prematurely removing records and media from your media 
database might make recovering that data tricky ....

Hello,

not shure, but i think this is some networker wiredness.
i think the question is why is mminfo keeping reverse dns old clients ?
shurely or probably the clients are not anymore in dns if they are dead.
for me, the problem is -  besides the "warnings" - that it seems because of 
reverse dns, mminfo is taking a lot of time waiting for timeouts. Why is mminfo 
asking reverse dns the whole bunch of (dead) clients ?

regards
