[root@www ~]# vim /etc/named.conf

Note: change named.localhost to forward.localhost and named.loopback to reverse.loopback as shown below.

options {
directory “/var/named”;
};

zone “mc712.com” IN {
type master;
file “forward.localhost”;
allow-update { none; };
};

zone “20.168.192.in-addr.arpa” IN {
type master;
file “reverse.loopback”;
allow-update { none; };
};

mc712.com is the domain name and http://www.mc712.com is the FQDN(Fuly qualified Domain Name).(Do not write http://)

IP ADDRESS is “192.168.20.34” that why we use “20.168.192“.

[root@www ~]# cd /var/named
