Understanding DNS Propagation

Before understanding the DNS propagation, you should be aware of the working of DNS. A master DNS is created by your web hosting provider in the event when you set your website up with it. 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.

How Your Website is Being Searched?

When an outsider source searches your website, it first switches to the registration database in order to find out about the DNS authority of your website. After then that it goes to the DNS sever of your web hosting service provider in order to find out the IP address of your website’s domain name. From this IP address, this outsider source locates your website and can view your website.
