I have all the files shipped with CentOS. I created 2 zone files, domain and reverse from the example in RHEL Documentation https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/7/html/networking_guide/sec-BIND#example-bind-zone-examples-basic 

https://paste.fedoraproject.org/paste/9-ZvmUg5vF-UI7lfuAIJjQ

I did find one typo in the domain zone but correcting that didn't help

Getent hosts localhost and getent hosts 127.0.0.1 returned no info.

Thanks!
