DNS forward and revorse Zone file

$ whatever file we gave in our named configuration file that files should be present in /var/named directory . Now we have to create the files.

# vim /var/named/forward.example.com

# vim /var/named/reverse.example.come

eeed

$ forward.example.com and reverse.example.com files group owner should be named

# chown root:named forward.example.com

# chown root:named reverse.example.com

$ After that check the configuration is correct or not

# named-checkconf -z /etc/named.conf

$ Then We need to check our zone file also

# named-checkzone forward /var/named/forward.example.com

# named-checkzone reverse /var/named/reverse.example.com

$ Restart the service 

# systemctl restart named
