A subdomain is part of a web address that's under the main domain, such as name.example.com. Technically, even in www.example.com the "www" element is a subdomain since the fully qualified domain name is just "example.com". Every subdomain can have its own website and records and can even be hosted using a different provider if you need to use a specific feature that is not offered by your current provider. A good example for using a subdomain is if you have a business site as well as an online store under a subdomain where customers can acquire your products. In addition, you can have a forum in which they can comment on the products and by using subdomains as opposed to subfolders you'll avoid any probability of all sites going down when you perform maintenance, or update one of the website scripts. Keeping the sites separated is more secure in case of a script security breach.
Subdomains in Shared Web Hosting
Every shared web hosting package that we offer will allow you to create hundreds of subdomains with no more than a few mouse clicks inside your hosting Control Panel. They're going to be listed in the area in which you create them and arranged under the main domain for more convenience, to help you very easily keep an eye on them all. Additionally, you can access many functions for any of the subdomains using right-click context menus - for instance, you can view or modify their DNS records, access the website files, and a lot more. While setting up a new subdomain, you will also have many options that you can pick from - define the default access folder, create unique error pages, activate FrontPage Extensions or pick if the subdomain is going to use a shared or a dedicated IP address. The amount of subdomains you are going to have is totally up to you because we have not limited this feature for any of our plans.
