BIND Reverse DNS Example Setup

Posted at October 8, 2015 at 1:45 pm by InterServer Staff

For this example we are using the IP block 216.74.109/24

In /etc/named.conf add:

zone “109.74.216.in-addr.arpa” {
type master;
file “/var/named/109.74.216.in-addr.arpa”
};

Create the following file:

/var/named/109.74.216.in-addr.arpa

Inside this file use the following example configuration:

$TTL 86400
@ IN SOA localhost. root.localhost. (
991079290 ; serial
28800 ; refresh
14400 ; retry
3600000 ; expire
86400 ; default_ttl
)
IN NS dns.trouble-free.net.
IN NS dns2.trouble-free.net.
81 IN PTR my.reverse.dns.domain.com.

Save your changes, then restart named using /etc/rc.d/init.d/named restart

A lookup of 216.74.109.81 would show my.reverse.dns.domain.com
