A subdomain is part of a web address that is under the main domain name, such as name.example.com. From a technical perspective, even in www.example.com the "www" part is a subdomain since the fully qualified domain name is only "example.com". Every single subdomain could have its own website and records and can also be hosted with a different company if you wish to use a feature that's not provided by your current service provider. An example for using a subdomain is if you have a company site and an online store under a subdomain where clients can purchase your products. You can even have a forum in which they can talk about the products and by using subdomains rather than subfolders you'll avoid any chance of all websites going down when you perform maintenance, or update one of the website scripts. Keeping your sites separated is less risky in case there is a script security breach.
Subdomains in Shared Hosting
Each and every shared hosting plan that we supply will enable you to create many subdomains with no more than a few clicks in your hosting Control Panel. They're going to be listed in the section where you create them and arranged under the main domain for more convenience, so you can effortlessly monitor all of them. Additionally, you can access lots of functions for any of the subdomains via right-click context menus - as an example, you can view or modify their DNS records, access the website files, and much more. While setting up a new subdomain, you will also have many options that you can pick from - determine the default access folder, create unique error pages, activate FrontPage Extensions or pick if the subdomain will use a shared or a dedicated IP address. What number of subdomains you are going to have is entirely up to you as we have not limited this feature for any one of our plans.
