Primary DNS server setup help

[Genco YILMAZ]

hi,
you can't use your private (non-routable over internet) IP block for  
your ns  records.
(If you want your domains to be public :)
Use your public IP address given to you by your provider in your NS records.
When you assign your public IP to your domain , your sub-domains will be 
reachable as well.
Don't worry about it..
