Your /etc/resolv.conf file should have the IP address for your DNS
server in there, an no external ones.

The "forwarder" configuration option in the named.conf file gives the
address for an external DNS server it'll query to answer anything that
it can't answer itself.

e.g. You ask your DNS server for the IP for google.com, and it doesn't
have an answer for it.  So, either it consults another DNS server listed
as a forwarder, and gives you its answer.  Or, if you don't have
forwarders configured, it goes to the root servers, finds out where to
make queries for ".com", then finds out where to make queries for
"google.com", then asks that server for the IP for "google.com".

I'd only configure forwarders if your ISP had good DNS servers.  Many
don't, and that's *why* some of us run our own DNS servers.  It's
certainly been the case for me, over about three different ISPs,
including two large national ISPs.

Don't send private replies to my address, the mailbox is ignored.  I
read messages from the public lists.
