Bind DNS Configuration issue.

Hi All,

I am trying to setup 2 node oracle RAC on 7.5 RHEL and for this it's required to setup DNS server. So i tried to configure DNS server in first server. I installed all the bind packages and configured files as below. named service is up and running. but dbs configuration is not working. could you please assist to fix this.

mainly configured below parameters in named.conf file

options {
listen-on port 53 { 127.0.0.1;192.168.43.10; }; <<<<<<<
# listen-on-v6 port 53 { ::1; }; <<<<<<<<<<<<<

recursing-file "/var/named/data/named.recursing";
secroots-file "/var/named/data/named.secroots";
