For some hosting package, we offer dedicated IP as part of our hosting package.
But for most accounts, we use shared IP when setting up your website.
You didnt really need a Dedicated IP in your hosting package unless if you plan to use SSL on your website,other than that whether you are using shared IP or dedicated IP make no difference at all.
However if your account package doesn't have a static IP, and you like to have a static IP, please create support ticket from http://helpdesk.seekdotnet.com
