Be wary of DNAME's; they can be quite limited. Here's an example from our old system:
internal. 3600 IN SOA mgmt1.mel.internal.local. sysadmin.external.com.au. 2014051201 28800 14400 3600000 86400 internal. 3600 IN NS mgmt1.mel.internal.local. internal. 3600 IN NS mgmt1.syd.internal.local. internal. 3600 IN DNAME external.com.au. Which means internally we can look up "host.internal" and it will translate to "host.external.com.au".

You're welcome. > The Grant Taylor tuto works like a charm!!! :) I'm glad that it worked for you. Note: I call this technique "Apex Override". I believe the Apex Override technique can be used anywhere you want to selectively override a (single) FQDN. I suspect there are some more nefarious things that you can do with this, particularly if combined with DNAME. But I try to keep my hit a lighter shade of gray. -- Grant. . . . unix || die _______________________________________________ Please visit https://lists.isc.org/mailman/listinfo/bind-users<https://urldefense.proofpoint.com/v2/url?u=https-3A__lists.isc.org_mailman_listinfo_bind-2Dusers&d=DwMFaQ&c=MOptNlVtIETeDALC_lULrw&r=udvvbouEjrWNUMab5xo_vLbUE6LRGu5fmxLhrDvVJS8&m=nupolP4thDlJODqxLEi-dEDhN8WVngTMx1q-ts6PxaA&s=E4pMIDm6PieL30gKBZtAGZE8Jedqx6UV_kvFvWxLdXE&e=> to unsubscribe from this list bind-users mailing list bind-users@lists.isc.org<mailto:bind-users@lists.isc.org> https://lists.isc.org/mailman/listinfo/bind-users<https://urldefense.proofpoint.com/v2/url?u=https-3A__lists.isc.org_mailman_listinfo_bind-2Dusers&d=DwMFaQ&c=MOptNlVtIETeDALC_lULrw&r=udvvbouEjrWNUMab5xo_vLbUE6LRGu5fmxLhrDvVJS8&m=nupolP4thDlJODqxLEi-dEDhN8WVngTMx1q-ts6PxaA&s=E4pMIDm6PieL30gKBZtAGZE8Jedqx6UV_kvFvWxLdXE&e=>
