When you purchase your domain with us, you will then either need to open a ticket and we'll add the domain for you or you can simply log into your cPanel then locate the option you need:
Click on on the option "Parked Domains", you will then be presented with the park domain admin panel in cPanel, enter your domain and click add. You don't need to add "http://" or "www".
By default the parked domain will be parked to on the cPanel main /public_html/ folder.
You will now see the domain is added and back on the main parked domain panel you will now see something like on the following image:
You will then be presented with a small form requesting where you would like the parked domain directing to.
Its a similar process to Parked domains. In cPanel click on "Addon Domains", then fill in the following form:
The form is self explanatory however one thing to note is that after entering your domain name some of the fields will auto fill including "Document Root" which is where this domain will point, this is also located within your /public_html/ folder that your main domain will be mapped to which means people will see your addon websites through the main cPanel domain. We recommend that you change this field to create a new directory outside of the /public_html/ directory, so for example enter "/public_addon_domains/your-domain.net/.
This way you keep a nice tidy directory of websites for easy management, also people won't be able to access your addon websites through the main domain which could cause confusion for users should they come across them, it could also adversely affect your search engine results if a bot tries to index two websites which have duplicate content through out.
You can also manage an addon domain at a later date.
