I am very puzzled because even on my old netbook which has only 2GB
ram, unbound (with standard parameters) is only 132 KB. So of course I
have the strong desire to drastically increase, but being pretty
clueless, I am also wary :)

Thank you a lot, sorry for my bad english. So it would be better to
have the LAN query a machine / gateway which runs the service, as
opposed to activating the service on each machine to take care of
itself?

One more question, is there a way to feed data to unbound cache? Such
as blacklists or already resolved whitelists? I can only imagine the
brute force and crude method of inserting a huge load of stuff into
HOSTS file, run a script that calls all those IPs while I supposedly
sleep (do we ever sleep?), then feed it another chunk until it's all
done. More elegant solutions?

Thank you again so very much
