Need advice on DNS

[Darren Poh]

Hi,

I have registered for a domain. Let take it to be 'mydomain.com'. The
registrar do not help me to host my new domain. I use the DNS service
by DNS-Made-Easy whereby I indicated 2 'A' records.

mydomain.com. with the address 111.222.333.444
ns0 with the same address

I want to run my own DNS (BIND 9 on Redhat 7.3) on my dedicated
server. Below is the content of my 'named.conf' file, follow by
content of the file 'db.mydomain.com'

*********************

// Authorized source addresses
acl "trusted" {
        localhost;
        111.222.333.444;
};

// Known fake source addresses shouldn't be replied to
acl "bogon" {
        0.0.0.0/8;
        1.0.0.0/8;
        2.0.0.0/8;
        192.0.2.0/24;
        224.0.0.0/3;
        169.254.0.0/16;
        // Enterprise networks may or may not be bogus
        10.0.0.0/8;
        172.16.0.0/12;
        192.168.0.0/16;
};

options {
        directory "/var/named";
        query-source address * port 953;
        allow-transfer { none; };
        allow-query { trusted; };
        allow-recursion { trusted; };
        blackhole { bogon; };
        version "OpenNA Linux";
};

logging {
        category lame-servers { null; };
};

controls {
        inet 127.0.0.1 allow { localhost; } keys { "mydomain.com"; };
};

zone "." IN {
        type hint;
        file "db.cache";
};

zone "mydomain.com" IN {
        type master;
        file "db.mydomain.com";
        allow-update { none; };
        notify no;
};

zone "0.0.127.in-addr.arpa" IN {
        type master;
        file "db.127.0.0";
        allow-update { none; };
        notify no;
};

zone "333.222.111.in-addr.arpa" IN {
        type master;
        file "db.111.222.333";
        allow-update { none; };
        notify no;
};

include "/etc/rndc.key";

Remotely, I am able to ping to 'mydomain.com' and also
'ns0.mydomain.com'. However, I am not able to ping to
'www.mydomain.com'. It seems like the content in my DNS configuration
is not been recognised by the 'outsie' world. I am not sure where went
wrong. I hope someone can provide me with some advice.

Thank you.
