If you cannot view your website after all this hard work then does it mean it that you are missing something or is it just something with DNS propagation?

This Master DNS is recorded in the Domain Name Server of your web hosting provider. The company which registers your domain name contacts to the DNS server of your web hosting provider. Your domain name registrar does it as the master authority of your domain which you have registered with it.
