What Is The Difference Between Addon Domain, Parked Domain & Subdomain?
What is an Addon Domain?
An addon domain is a fully functional domain that can be created from within your control panel. This addon domain is a new, unique website hosted in a new folder on your account so that you can host several domains from one control panel. You can give an addon domain email addresses, forwarders, and more the same way as a primary (main) domain on the account.
When you create an Addon domain, 3 things happen:
- a folder is created in the 'public_html' directory
- a subdomain is created for the primary domain and attached to the new folder
- the new domain name is associated with the subdomain
For example, if the primary domain was 'abc.com' and you assign the Addon Domain '123.com' to the folder '123', the following routes (URLs) would be true:
All three of these paths would access the same directory and show the same website. However, in concern to your website's viewers going to 123.com, there is no evidence that they are being routed through 123.abc.com and everything will function as normal.
This all happens automatically when an Addon domain is assigned to an account; there is no need for further action necessary other than loading content into the addon domain folder.
Additionally, for those still concerned with 123.abc.com being active, there is a method in which you can disable the 123.abc.com route from accessing the site without disturbing the 123.com route. This can be found in our knowledge base article: Restrict subdomain access to addon domains
What is a Parked Domain?
A parked domain is an alias of your primary domain — it points to the same website as your primary domain. Multiple domains, same website.
For example, if cars.com is your main web site, you can purchase cars.net and assign it as a parked domain. Then, if a visitor were to go to cars.net, they would see the same website as if they had typed cars.com.
In other words, both primarydomain.com/index.htm and parkeddomain.com/index.htm will point to the same webpage "index.htm".
What is a Subdomain?
A subdomain is a prefix added to your original domain name, like a domain within a domain, usually following the form subdomain.example.com. They behave very similar to an addon domain and are often created to separate different sections of your website, such as blog.example.com or store.example.com.
You can create a subdomain from Domains > Subdomains within your control panel.
Note: Domains can be assigned and unassigned from the Domain Manager. The steps for accessing the Domain Manager will vary depending on which type of account you have. To begin, you will need to sign in to your Bluehost account. To learn more about it, please refer to this article, How To Assign A Domain Name - A Record, Name Servers, HTML Page.
