A subdomain is part of a web address that's under the main domain, such as name.example.com. From a technical perspective, even in www.example.com the "www" part is a subdomain given that the fully qualified domain name is just "example.com". Every subdomain could have its own site and records and can even be hosted using a different company if you want to use a specific feature which isn't provided by your current provider. One example for using a subdomain is if you have a business site and an online store under a subdomain where clients can acquire your products. In addition, you can have a forum in which they can talk about the products and by using subdomains rather than subfolders you will avoid any probability of all websites going down if you perform maintenance, or update one of the website scripts. Keeping your sites separated is also more secure in the event of a script security breach.
Subdomains in Hosting
When you use hosting packages you will be able to create subdomains with only a couple of clicks in your hosting Control Panel. All of them are going to be listed in one place together with the domains hosted in the account and grouped under their own domain so as to make their managing simpler. No matter the plan that you select, you will be able to create many subdomains and set their access folder or set up custom error pages during the process. You will also have access to a lot of functions for any of them with just a mouse click, so from the exact same section where you create them you can access their DNS records, files, visitor statistics, etc. Unlike other companies, we have not limited the amount of subdomains you can have even if you host only one domain address inside the account.
Subdomains in Semi-dedicated Servers
When you purchase a semi-dedicated server package, you'll be able to create as many subdomains as you want as this feature is unlimited. For the reason that the web hosting plans are quite powerful, we've decided not to put any restriction on the number of subdomains. Our advanced Hepsia Control Panel will enable you to create a new subdomain with no more than a couple of mouse clicks, to pick which folder it'll access in the account, to enable FrontPage Extensions for it, to create custom error pages, to create a shared or a dedicated IP address if you have one, and more. For your convenience, all the subdomains are going to be listed under their root domain, allowing you to easily see and handle them. Through fast access links, you'll be able to open the website files for each of the subdomains that you have or see its DNS records.
