Hello,
I went ahead and rebuilt your /etc/named.conf file to resolve this issue. Here are the commands I ran:
[16:02:09 s3 root@4332467 ~]cPs# mv /etc/named.conf /etc/named.conf_bak_20130828
[16:03:45 s3 root@4332467 ~]cPs# /scripts/rebuilddnsconfig
./
./localdomain.zone
./localhost.zone
./named.broadcast
./named.zero
./named.local
./named.ip6.local
Including rndc key file to named.conf
Adding controls clause
[16:03:54 s3 root@4332467 ~]cPs# service named restart
Stopping named: .                                          [  OK  ]
Starting named:                                            [  OK  ]
The first one backed up the previous /etc/named.conf, the second command  built a new one, and the final command restarted the service. Now when I  go to 
http://intodns.com/zarinhosting.tk  it loads the correct information (though you will probably need to  contact your ISP/hosting provider to setup your PTR record). Please let  us know if you have any questions.
