This sub-domain vs parked domain vs add-on domain comparison is made for beginners who are puzzled about their differences. After all, all of them can be regarded as a part of your main domain, and have been allowed by many web hosts without clear limitations.

In the following, we’d like to unveil the hosting secrets of these three kinds of domains, including their definitions, functions, differences among each other and the methods to enable them.

About Sub-Domain

The sub-domain is the subdivision of your primary domain name, which points to a folder in the public_html directory. With it, you can set up an independent section of your website with its unique content, such as the blog area, forum, community, photo gallery and many more.

Generally, the sub-domain is used by some large websites that have multiple categories or are targeting different regions all over the world. Even, some medium-sized websites may also use the sub-domain to add the inner blog area or forum area for better online communication with readers.

  • Scroll the webpage down to “Create a Subdomain” section, and enter the prefix of your sub-domain.
  • Enter “public_html” in the field of Document Root.

About Parked Domain

The parked domain does not lead to a separate site. Instead, it directs your readers to your main website using the primary domain. For instance, if your main domain is and you have assigned the as your parked domain; then people just access the same website no matter which domain they enter into their browsers.

The parked domain is commonly used when your main domain is long, but you want to have a short version for email addresses. Also, if your primary domain has some misspelling issues when registered, the parked domain can come into handy to better attract online visitors. Even, if you have chosen a good domain and assigned it to your parked one, your website traffic can be boosted greatly.

How to Add a Parked Domain

  • Log into your control panel and click the “Parked Domain” icon under the sub-header of “Domains”.
  • In the section of “Create a New Parked Domain”, you simply need to enter the domain name you’d like to park on your primary one.
  • Hit the Add Domain button.

About Add-On Domain

The add-on domain is much like the sub-domain, allowing you to create a separate and unique website from your main site within the same hosting account. However, the difference is that this kind of domain requires you to register before hosting it, and should be pointed to the same nameservers as your main domain. Besides, although the add-on domain does not have its own control panel, it still allows you to add email accounts.

This type of domain is used when you are looking to set up another independent website, but do not want to purchase additional hosting service.

How to Add an Add-On Domain

  • Log into your control panel and click the “Addon Domain” icon.
  • Target the section of “Create an Add-on Domain” and enter the required information, including the domain name you are adding to your hosting account, the FTP username that is configured by your control panel automatically, “public_html” for the Document Root and the exclusive password for FTP.
  • Click the Add Domain button.

Add an Add-On Domain
