More newbie questions

[Pons, Eric]

I have successfully installed BIND 8.2.4 on Linux with the default setting
and zones which enable me to resolve internet names, which is what I want to
do. What I would like to know is, do the names that get resolved, does that
data get saved somewhere? If not, is there anyway for me to setup a DNS
server that only resolves internet (not local) names that would be more
efficient than these default settings? That would have a file that is
keeping a dynamic list of names and their resolved addresses? Any input
would be very appreciated. Thank you.
