Addon Domains

Addon Domain is a hosting feature that allows you to add additional domains to the same hosting account. With a domain addon, you can run several websites with different domain names, but all of them use the same hosting resource.

Detailed Explanation

Technical Definition

An addon domain is a secondary domain that is added to an existing hosting account, where the domain has a separate directory from the main domain (primary domain).

Each domain addon can have:

• Special subdirectory in the hosting file manager
• Email accounts with the domain name
• Separate database
• Independent traffic statistics
• Different SSL certificates

History & Development

The addon domain concept became popular in the early 2000s when shared hosting became mainstream. Previously, each domain required separate hosting, which made it expensive to manage multiple websites.

Hosting providers like cPanel introduced this feature to:

• Optimize the use of server resources
• Provide more value to customers
• Makes it easier to manage multiple domains

How Addon

Domains Work

Step-by

• Step Process

Here's the workflow when a user accesses your addon domain:

1. DNS Resolution - User types the addon domain in the browser
2. Nameserver Lookup - DNS points to the hosting server
3. Virtual Host Processing - The hosting server recognizes the domain
4. Directory Mapping - The server directs to a specific folder
5. Content Delivery - Website files from the folder are displayed

Folder Structure

This is how the hosting folder structure with addon domains looks like:

public_html/
├── index.html

# Domain utama
├── assets/  # Assets domain utama
├── addondomain.com/  # Folder addon domain
│├── index.html

# Homepage addon domain
│└── assets/# Assets addon domain
└── mail/# Email accounts

Real

• World Example

For example, you have a business like this:

• Main domain: tokobaju.com (online clothing store)
• Addon domain 1: resepmasakan.com (recipe blog)
• Addon domain 2: portfoliosaya.com (personal portfolio)

These three websites run on the same hosting account, use one IP address, but display different content according to the domain being accessed.

Result: You save 3x the hosting costs, but can still manage 3 different websites!
