Addon domains allow you to control multiple domains from a single account. An addon domain links a new domain name to a directory in your account and then stores its files in that directory.
1. You need to click on the Addon Domain icon. Here, you can set up additional domain names that can relate or connect to the sub domains you have created.
2. Enter the new domain name, enter the username, give the root, and then the password.
3. Hit the add domain button in order to generate Addon domain.
4. With this, you can create the addon domain and can further use it.
