Understanding Sub-Domains and Add-On Domains in Web Hosting

Sub-Domains and Add-On Domains

If you know the ins and outs of web hosting, you must have heard of sub-domains and add-on domains. If you buy a domain name right now, you can easily add a second URL on top of your original URL. This additional or second domain name is known as sub-domain or add-on domain. What you need to know, however, is that this second URL lacks a control panel. But it will have its CGI and index bin folder.

  • Differences between add-on domain and sun domain in web hosting

Ideally, two kinds of additional URLs exist; Add-on and sub-domain. The difference between the two lies in how they are created and used. After creation, an add-on domain usually comes with its URL. An add-on domain name example is www.bestechnology.com. On the flip side, a sub-domain is a URL tethered to its primary domain. An example of a sub-domain is mail.bestechnology.com.

  • Add-on domain and sub-domain can be differentiated based on price

Sub-domains can be acquired free of charge. With add-on domains, you have to pay for URL registration. Typically, you’ll be required to pay monthly or annual fees to maintain it as it happens in a typical domain name. Why is that? You might ask; because add-on domain comes along with a host of benefits. For example, your add-on domain will enjoy all the features and add-ons extended to your primary domain name. Essentially, the sub-domain will have its FTP, page statistics and much more.

  • How to embed your add-on domain to your web hosting account

It’s quite easy to get your add-on domain to your web hosting server. First, you need to perform domain name registration and acquire a domain name. After you acquire the domain name, link your domain name server to the hosting provider. You’ll then need to log into your web hosting company’s cPanel and locate a feature known as Add-On Domains. The next step is to key in your domain name details and install it. After installation, choose ‘start’ and give it time until the installation process is complete.


A lot of website owners use add-on domain names and sub-domain for different reasons. However, most use them to create multiple websites, using many domain names, without the need to use multiple web hosting solutions. Website owners who have a site with little traffic or those looking to create one and don’t require a dedicated web hosting service often choose to go with an add-on domain instead of signing up with a separate web hosting company. Besides giving you the opportunity to host multiple websites, add-on domain saves you a lot of money along the way.
