LinuxQuestions.org - DNS server for local network

I want to configure nameserver for local area network. My registered host in Internet DDNS system is <my_host>.ddns.net

I want to use for my local network usage (not Internet) internal address like:

host1.ddns.net
host2.ddns.net
etc
and of course router as <my_host>.ddns.net

As I wrote I use NO-IP DDNS system to access from internet my router (and the rest of local network by ports) as <my_host>.ddns.net

So my zone definition file looks like this:

Code:

[root@mackowiak named]# cat ddns.net.hosts 

$ttl 38400

ddns.net.      IN      SOA    mackowiakp.ddns.net. 192.168.0.7 (

                        1431270668

                        10800

                        3600

                        604800

                        38400 )

ddns.net.      IN      NS      mackowiakp.ddns.net.

mackowiakp.ddns.net.    IN      A      192.168.0.7

tv.ddns.net.    IN      A      192.168.0.121

localhost  IN      A    127.0.0.1

so if I query form local network, local network located nameserver it answers correctly. Just like example below:

Code:

[maciek@piotr ~]$ nslookup tv.ddns.net 192.168.0.7

Server:        192.168.0.7

Address:        192.168.0.7#53



Name:  tv.ddns.net

Address: 192.168.0.121

but if I query about physically existing in ddns.net domain node, but not located in my local network it can not find out it. Just like in example below:

Code:

[maciek@piotr ~]$ nslookup lilith.ddns.net 192.168.0.7

Server:        192.168.0.7

Address:        192.168.0.7#53



** server can't find lilith.ddns.net: NXDOMAIN

This is my named.conf file:

Code:

[root@mackowiak named]# cat /etc/named.conf



options {

        listen-on port 53 { any; };

        directory      "/var/named";

        memstatistics-file "/var/named/data/named_mem_stats.txt";

        allow-query    { localhost; 192.168.0.0/24; };

        recursion yes;



        dnssec-enable no;

        dnssec-validation no;

        dnssec-lookaside no;



        forwarders {

                208.67.222.222;

                208.67.220.220;

                };

        forward first;

};



logging {

        channel default_debug {

                file "/var/named/data/logi";

                severity dynamic;

                };

};





zone "ddns.net" {

        type master;

        file "/var/named/ddns.net.hosts";

        };

How to set up DNS server to work that way that all queries to local DNS about ddns.net domain will will be forwarded to any public DNS server, if not found in local DNS.
Of course proble is only with ddns.net domain because other domains/hosts are resolved properly. Just like this:

Code:

[maciek@piotr ~]$ nslookup www.playboy.com 192.168.0.7

Server:        192.168.0.7

Address:        192.168.0.7#53



Non-authoritative answer:

www.playboy.com canonical name = g.global-ssl.fastly.net.

Name:  g.global-ssl.fastly.net

Address: 185.31.17.65

Is it possible at all? Any help please!
