Addon domains allow you to host multiple websites with a single hosting account. Each addon domain looks and works like a completely separate website, even though it uses the same hosting plan.
This guide explains what addon domains are, how they work, and how you can set them up step by step.
What Is an Addon Domain?
An addon domain is a fully functional domain that you can add to your hosting account. After setup, the addon domain works like a standalone website with its own:
Website files
Email accounts
Subdomains
Unlike subdomains (like blog.yourmaindomain.com), addon domains have their own unique domain names (like yournewsite.com), but share space in the same hosting plan.
Why Use Addon Domains?
Here are the main benefits of addon domains:
✔ Host multiple websites using one hosting plan
✔ Manage all sites from the same control panel
✔ Save money compared to buying separate hosting for each site
✔ Separate content and emails for each domain
Addon domains are perfect if you want to start more than one site without paying for multiple hosting accounts.
Before You Start
Make sure you have the following ready:
✔ You Own the Domain
The addon domain must already be registered with a domain registrar.
✔ Nameservers Are Updated
Make sure the domain’s nameservers point to your hosting provider’s servers. If not, update them and wait for propagation.
✔ DNS Propagation May Take Time
After updating nameservers, changes may take up to 24–48 hours to spread worldwide.
How to Add an Addon Domain (Step by Step)
Follow these steps to add an addon domain to your hosting account:
Step 1: Log in to Your Control Panel
Sign in to your hosting control panel using your account credentials.
Step 2: Navigate to the Addon Domain Section
Look for the Addon Domains tool under the Domains section in your control panel.
Step 3: Enter the Domain Details
You’ll see a form asking for:
New Domain Name – Enter your addon domain (e.g.,
yournewsite.com)Subdomain/FTP Username – Automatically filled, but you can change it
Document Root – The folder where the site’s files will be stored
Make sure the document root folder is unique for this addon domain.
Step 4: Click “Add Domain”
Once you fill in the details, click the Add Domain or Create button.
Your new addon domain will be created, and a folder will be added to your hosting file structure.
Upload Website Files
After creating the addon domain:
Go to File Manager or connect via FTP
Open the addon domain’s root folder
Upload your website files there
Now the addon domain is ready to host its own website content.
Install Applications (e.g., WordPress)
You can install WordPress or other applications on your addon domain just like a primary domain:
Use your one-click installer
Choose the addon domain from the installation dropdown
Complete the setup
Each addon domain works independently.
Create Email Accounts for the Addon Domain
You can create separate email accounts for your addon domain:
Example:
[email protected] [email protected]
Go to the Email Accounts section in your control panel and choose the addon domain when creating new addresses.
