Trust me, Cpanel is going strong with a really large market share and it’s quite good for hosting multiple domain names. You have multiple choices:

1. Add-on domains
You have a main site account and you can add on domains that will reside under your homedir as a new folder however it also works with own domain name.

2. Reseller account
Create new account per domain and there you go. The best option of course and best recommended.

3. Normal account per web site
If you have a dedicated server running Cpanel you create new account per site as you would with a full reseller account.

With Cpanel hosting multiple domain names is easy.

Simple math – I have 3 domains paying $9 per month for each web site – my monthly hosting expenses are $27. I found a multi domain name hosting provider that charges me $20 monthly so I save $7 per month. I can save much more if I register new domain names and launch the web sites. The only drawback is that usually you can have one main user that manages all multiple domain web sites. You cannot share it with others or you break the service agreement.

The only drawback is that if the server goes down, all your sites that are hosted on one multi domain hosting account will be down….
