cPanel or Control Panel solutions have offered cPanel hosting which enable the user to host their own domain or any webmail accounts. The interface analytics have made major changes to the way users interact with cPanel, and has definitely improved the ability to navigate a lot easier.
cPanel hosting is technically Linux based hosting, which allows the user to manage their Webmail accounts and other domains that they have, under a single tab. Not only is it efficient, but is also extremely cheap considering how much a user has to pay in order to get started with all the things separately.
When a user gets started with their cPanel account, they are provided a basic or a temporary (in this case) URL, which can be used to access their own server and make changes when necessary.
The Temporary URL will look something like: http://IP/(username)
This Username will be the one that one chooses when they are setting up their cPanel account. The IP will be the host IP address or the Internet Protocol address of the host server. The reason that cPanel provides is to let the users test the temporary URL with any other server (merge them) before the user actually starts working on the DNS records of the same server.
The temporary URL will no longer be valid after DNS records are implemented or might not work with some of the sites. To access those sites, one can configure or change the default or temporary URL and then proceed with either the server merging or access DNS records of the said server.
Note: If you want your domain to run public DNS entities, you must manually remove the Domain name and the IP address from /etc/hosts file, before proceeding with alteration of the hosts files.
