How to Map a domain name with a Linux server using public IP?
If you want to access your website with a domain name rather than an IP address which is difficult to remember. We need to purchase a domain name from a provider (eg: GoDaddy) and link the domain with the public IP address on which you currently host your website files using DNS Settings.

Introduction:

If you have not changed any DNS settings after purchasing your domain. Then by default, your domain name will be in a parked state. That means when you visit your domain name it will redirect to some sample page without showing a blank page.

To change the state of your domain name from Parked state to Live state. You have to delete an A record ( with fields mentioned as Parked on it ) from the DNS settings. To read more about DNS records click here.
