In doing so I noted that the default named.conf file provided contains no less than 161 pre-defined zones that all point to: /usr/local/etc/namedb/master/empty.db These zones are prefaced with the following statement: /* Serving the following zones locally will prevent any queries for these zones leaving your network and going to the root name servers. This has two significant advantages: 1. Faster local resolution for your users 2. No spurious traffic will be sent from your network to the roots */ So, what happened to the 'empty-zones-enable' and 'disable-empty-zone' options? Why are these zones explicitly defined? -- *** e-Mail is NOT a SECURE channel *** Do NOT transmit sensitive data via e-Mail Do NOT open attachments nor follow links sent by e-Mail James B.
