A) $ORIGIN changes appended suffix to all hostnames without trailing . for all following records. You can change it more than one time. Unless I am mistaken, NS records of first section would expand to . NS local.atlanta.com. . NS kabulvm8.atlanta.com.
That seems wrong to me. B) Yes, it is almost equal. NS records are correct this time. I would prefer this variant myself. However if those zones are output of some tool or script, you should try to support multiple usage of $ORIGIN directive in any tools you use. -- Petr Menšík Software Engineer Red Hat, http://www.redhat.com/ email: pemen...@redhat.com PGP: 65C6C973 ----- Original Message ----- From: "Harshith Mulky" <harshith.mu...@outlook.com> To: bind-users@lists.isc.org Sent: Wednesday, December 21, 2016 1:57:35 PM Subject: Need of 2 $ORIGIN Directives Hello, We have bind running bind-9.9.4-29.el7.x86_64 We have a domain file with these configurations and we have to build our A records on top of this $ORIGIN . $TTL 86400 ; 1 day atlanta.com IN SOA local.atlanta.com. master.atlanta.com.
