Sure, and if you don't have recursive lookups turned on, then YOU can't
use the DNS server, so whose server will YOU use?

Yes, you can disable it in the /etc/named.conf file (see "man named" or
the "cricket" book, "DNS and Bind" from O'Reilly), but if you do, you'll
have to use some other nameservers for your own resolution needs, and
any changes you make to DNS may overwrite your changes.
