They point to *some* name servers. They may or may not be local, depending on what you mean by local and the details of your configuration. : If you send a query to one of your local name servers : for broken-dns.com, and that name server tells you that broken-dns.com : doesn't exist, it does not good to send this query to the rest of : your local servers, since they'll just send a similar set of queries : out to the Internet, get similar responses, and finally tell you that : broken-dns.com doesn't exist. This is the theory of dns, but in practice this is not the case. NXDOMAIN replies are issued in cases where a valid mapping exists, and can be obtained from another name server. Repeating this fact is now wearisome. To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-net" in the body of the message
