A subdomain is part of a web address that's under the main domain, such as name.example.com. Actually, even in www.example.com the "www" part is a subdomain given that the fully qualified domain name is only "example.com". Each subdomain can have its own website and records and can also be hosted using a different company if you want to use a specific feature which is not provided by your current service provider. An example for using a subdomain is if you have a business website and an online store under a subdomain where customers can purchase your products. You can even have a forum in which they can discuss the products and by employing subdomains as an alternative to subfolders you will avoid any probability of all sites going down when you perform maintenance, or update one of the website scripts. Keeping the sites separated is also more secure in the case of a script security breach.
Subdomains in Web Hosting
Every web hosting plan we supply will enable you to create hundreds of subdomains with no more than a couple of mouse clicks in your website hosting CP. They will all be listed in the section where you create them and grouped under the main domain for more convenience, to help you very easily keep tabs on every one of them. Furthermore, you can access a lot of functions for any one of the subdomains via right-click context menus - for instance, you can view or edit their DNS records, access the site files, and more. While setting up a new subdomain, you're also going to have a number of options that you can pick from - specify the default access folder, set customized error pages, activate FrontPage Extensions or select if the subdomain will use a shared or a dedicated IP address. What number of subdomains you are going to have is completely up to you since we have not limited this feature for any of our plans.
