An addon domain is a separate, fully functional website that you can host under your primary hosting account. It allows you to manage multiple websites from a single control panel without purchasing separate hosting plans for each one. Think of it as adding an extra apartment to your existing property—both are independent but managed from the same location.

To set up an addon domain, you typically need to:

• Register a new domain name or use an existing one you own.
• Access your hosting control panel (like cPanel).
• Navigate to the "Addon Domains" section.
• Enter the new domain name and specify a directory (folder) for its files.

Once configured, the addon domain will have its own:

• Website content (stored in the assigned directory).
• Email addresses (e.g., info@youraddondomain.com).
• Visitor statistics and logs.

Key benefits include cost savings (no extra hosting fees) and centralized management. However, all addon domains share the resources (like disk space and bandwidth) of your main hosting plan. Ensure your plan has sufficient resources to support all your websites.

Use addon domains for separate business projects, blogs, or family sites. Remember, while they operate independently, they are tied to your primary account’s renewal and security. Always keep your main account secure to protect all addon domains.
