# Addon Domain

## What is an Addon Domain?

An **addon domain** is an additional domain name you can add to your hosting plan. It operates independently from your primary domain, allowing you to host multiple websites under a single account.

### Key Features of Addon Domains:

* **Full Functionality**: An addon domain can have its own website, email addresses, and forwarding settings, just like your primary domain.
* **Directory Structure**: When you create an addon domain, a folder with the domain's name is created in your root directory, unless you specify a different name or path.
* **Subdomain Creation**: A subdomain (e.g., `[addon].maindomain.com`) is automatically created and linked to the new folder for previewing purposes.

### Adding an Addon Domain:

* **Log into cPanel** and navigate to the **Domains** section.

* Enter the desired domain name in the appropriate field.
* Specify the document root location in the last field.

#### Important Note:

* The addon domain must be registered before users can access it.
* If you enter a domain that resembles an existing one on your account, the system will recommend creating a subdomain instead.

### Creating Multiple Addon Domains with Different Extensions:

* To create multiple addon domains (e.g., `example.net` and `example.com`), manually enter a unique username in the Subdomain text box.

### Limitations and Configuration:

* The maximum number of addon domains you can create is displayed in your cPanel Statistics Sidebar. For resellers, this number can be modified via WHM under **List Account > Modify Account > Max Addon Domains**.
* If you encounter errors due to incorrect zone files for the registered domain, you can use the **Zone Editor** in cPanel to correct them.

> **Note**: If you're unsure about your zone files, please reach out for assistance to ensure everything is set up correctly.
