At EZProvider, we allow you to host unlimited domains under every account. The trick is there are really two ways to setup the domains.

First, you can create the domains as an add-on domain using cPanel. The second method is to login to WHM and create a new account. There are advantages and disadvantages to each method.

Add-on domains via cPanel:

• Easy to manage: with your cpanel account login you can control all your add-on domains. They are actually setup as sub directories of your account, so there are no multiple username/password combo's to keep track of - if you wish you can simply have 1 ftp account to manage all of your domains.
  * You can however create separate FTP users for the add-on domains if you wish.
  * You can create email addresses for add-on domains.
  * Add-on domains do not get their own cPanel login, you must manage add-on domains with your main cPanel account.
  * Add-on domains do get unique stats, but by default they do not get a login to view these stats - only your main cPanel account can view them. There is a work around, but it takes some knowledge to implement.

Creating a new account via WHM:

• Full cPanel access, can even create it's own add-on domains!
  * You can set account limits for drive space and bandwidth, email accounts, etc.
  * Has a unique username and password.
