FreeBSD comes with a list of "root" DNS servers. These are master servers maintained by many different sources that have information on the top level domains. From this list, the DNS can figure out which root server to contact for .com or .net or .whatever. That server then directs your server to the specific DNS server that has the information you are asking for. This is oversimplified. If you have forwarders configured, then the forwarders check their cache first, before consulting the root servers. But the basic method is described there. -- Bill Moran Potential Technologies http://www.potentialtech.com To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
