I just installed bind on RHEL 6 and point a domain to that server. but actually when i ping domain it returns error 1214: Here is my named.conf:

//
// named.conf
//
// Provided by Red Hat bind package to configure the ISC BIND named(8) DNS
// server as a caching only nameserver (as a localhost DNS resolver only).
//
// See /usr/share/doc/bind*/sample/ for example named configuration files.
//

options {
        listen-on port 53 { any; };
        listen-on-v6 port 53 { ::1; };
        directory       "/var/named";
        dump-file       "/var/named/data/cache_dump.db";
        statistics-file "/var/named/data/named_stats.txt";
        memstatistics-file "/var/named/data/named_mem_stats.txt";
        allow-query     { any; };
        recursion yes;

        dnssec-enable yes;
        dnssec-validation yes;
        dnssec-lookaside auto;

        /* Path to ISC DLV key */
        bindkeys-file "/etc/named.iscdlv.key";

        managed-keys-directory "/var/named/dynamic";
};

logging {
        channel default_debug {
                file "data/named.run";
                severity dynamic;
        };
};

zone "." IN {
        type hint;
        file "named.ca";
};

include "/etc/named.rfc1912.zones";
include "/etc/named.root.key";
zone "mydomain.com"{
        type master;
        file "/var/named/data/named.mydomain.com";
        allow-update { none; };
};

AND The content of "/var/named/data/named.mydomain.com":

1 $TTL 38400

2

3 mydomain.com. IN SOA ns1.mydomain.com. milad.yahoo.com. (

4 2012101201 ; serial number YYMMDDNN

5 28800 ; Refresh

6 7200 ; Retry

8 38400 ; Min TTL

11 mydomain.com. IN A 1.2.3.4

12 www IN A 1.2.3.4

13 ns1.mydomain.com. IN A 1.2.3.4

14 ns2.mydomain.com. IN A 1.2.3.4

15 mydomain.com. IN NS ns1.mydomain.com.

16 mydomain.com. IN NS ns2.mydomain.com.

AND i'm sure the named service is running:
