Difference Between Parked Domain, Add-on Domain and Sub Domain

updated on Dec 29, 2014
Difference Between Parked Domain, Add-on Domain and Sub Domain As many people are puzzled by the differences among parked domain, add-on domain and sub domain when they start a website with a web hosting plan, this article provides detailed information on their definitions and usages. Note that the creation of each kind of domain on your hosting package may differ depending on the control panel offered.

Parked Domain

A parked domain is a separate domain that is independent from the primary domain in the address (URL). However, the difference is that parked domains share the same web content as the primary one, which means that when you type a parked domain in the address bar, you see a webpage that is absolutely the same as that of the primary domain.

Now we assume that you have 3 domains as domain1.com, domain2.com and domain3.net, among which the domain1.com is the main domain of your website. If you park domain2.com and domain3.net on the main domain, we will get the same page as the main domain when we type either of the 2 domains.

Note that parked domains should be registered and point to the same name servers as the main domain, and you cannot use a parked domain for a separate website until you unpark it.

When Should You Use Parked Domains?
When Should You Use Parked Domains Parked domains are commonly used in multiple situations, among which one of the most usual is to protect and increase traffic. If you have an eCommerce business named Business, it is probably that you think about using Business.com as the official site. However, people not very familiar with the domain are likely to try other domains like Business.net to access your site. In the case that these domains have been registered, the traffic which should be yours is gone especially when the domains are also used for eCommerce.

For businesses, registering multiple domains with different suffix or similar spelling is worth the money as it expands the business, increases sales, as well as protects the brand from being used illegally in some cases.

When you attempt to use parked domains, you should carefully choose a domain name with the right suffix, register it with a reputable and reliable registrar, and then update the domain name servers to be the same ones as the primary domain to make it work. The last step does not need to be done when you register the domain directly with your web host.

Add-on Domain

Being different from parked domains which are completely separate domains but point to the same websites as the primary domain, each add-on domain directs visitors to an independent website that has nothing to do with the site of the primary domain. In this way, you are able to host multiple websites with one hosting account to simplify the management and reduce costs.

Add-on domains function in the same way as the primary ones. You can create email addresses for it, set up email forwarders, create FTP accounts with new username and password, manage software installation, add subdomains, and do more things just like what you have done to the primary domain. They do not have their own control panel, but share the same one as the primary domain.

Important Things to Know About Add-on Domains
Important Things to Know About Add-on Domains When setting up an add-on domain, you actually create a brand new folder in the "public_html" directory. When the process is done, you can simply upload content to the folder to make the new site active. Whatever you do to the new domain, the changes do not have any influence on the primary domain.

In the process of creating, a subdomain which is attached to the new folder is created automatically for the primary domain and connected to the new add-on one. In this circumstance, you can access the new site with 3 different routes – the add-on domain name, the subdomain name, and the name of the subfolder. For example, if you have a primary domain of yourdomain.com and an add-on one of addondomain.com, the URLs available for accessing are (in the case that the name of the folder is addondomain):
  • //addondomain.com/
  • //addondomain.yourdomain.com/
  • //yourdomain.com/addondomain/

Sub Domain

A subdomain is a third level domain that works as a part of a larger top level domain name. It is a second website which has its own content but shares the same domain as the larger domain name. When you create a subdomain, there is a special URL that can be used to access a certain part of your existing website.

In the case that you want to divide your site content into several separate parts for better organization or want to add additional functionality to the site, using subdomains is a good and efficient way. For example, supposed that you have already had a domain yourdomain.com and would like to build a store page on the site, you can create a subdomain for the store part to allow people to access the store by visiting //www.yourdomain.com/store or //store.yourdomain.com/.

Why Use Subdomains?
Why Use Subdomains Subdomains are usually used to organize website content, but it is also created for some other purposes sometimes. With the utilization of subdomains, you can set up a store, a forum, a blog and many other pages on one website instead of spending money purchasing multiple domains to get them separate and independent from each other. As subdomains also have their own email addresses like orders@store.yourdomains.com, they are quite convenient for companies to use.

In addition, if you own a website and have several people contributing and managing it, you need subdomains. By creating subdomains for separate parts that the members are responsible for, you can give different access to each member and restrict their permissions to the site to ensure the security of the whole website.

How to Create Or Remove a Subdomain?
Creating a subdomain is a simple task to accomplish while you should make sure that the domain makes sense in spelling so that it is easy for people to remember. Note that if your main domain is not pointed to the nameservers of your web host, you should update the domain name server first before creating any subdomain, or you should create subdomains where the current nameservers are hosted.

How to Create Or Remove a Subdomain Assumed that everything is right, you need to follow the steps below to get a subdomain created in cPanel.
  1. Log into cPanel control panel.
  2. Navigate to the Domains section, locate Subdomains and click on the link.
  3. In the Create a Subdomain section, enter the name of the subdomain, and in the dropdown menu, choose the domain name that you want the subdomain to create for.
  4. Have a click in the box next to Document Root, and a folder is generated automatically which stands for the location where the subdomain loads content. For instance, if you have typed in blog as the subdomain, the document root field should be /public_html/blog.
  5. Click the Create button.

Now a subdomain is created successfully. In most cases, it takes 12-36 hours for the domain to get available on the web. There is one thing to pay attention that if you have several domains and would like to add a blog to each of them, you should not use the default value of the document root because doing so results in that all of //blog.yourdomain1.com, //blog.yourdomain2.com/ and so on load the same content. To prevent this from happening, you need to create unique document root for each of the subdomains like /public_html/blog1 (blog2) to get them apart from each other.

Below are the steps that need to do to remove one from your hosting account.
  1. Log into cPanel, find the Subdomains link and click on it.
  2. Find the subdomain you'd like to delete in the list and click the Remove link in the Actions column.
