Create the Zone:
[root@ns01 ~]# cat /etc/named/named.conf.local
zone "DOMAIN.com" {
type master;
file "/etc/named/zones/db.DOMAIN.com";
};
zone "REVERSEIP.in-addr.arpa" {
type master;
file "/etc/named/zones/db.REVERSEIP";
};
where REVERSEIP would be 1.168.192 if your range would be 192.168.1.0
Then add the Zone:
[root@ns01 ~]# cat /etc/named/zones/db.REVERSEIP
$TTL 604800
@ IN SOA DOMAIN.com. admin.DOMAIN.com. (
23 ; Serial
604800 ; Refresh
86400 ; Retry
2419200 ; Expire
604800 ) ; Negative Cache TTL
; name servers
IN NS FQDN_NS.com.
; PTR Records
32 IN PTR REC1.com.
Last entry would be REC1.com reverse lookup ip: 192.168.1.32
