Each website on the Internet must have an IP number. When you buy a hosting package, the website gets a Shared IP number, which means your website has the same IP number of the another website from the same server. Some websites need a Dedicated IP to increase the security among other goals.
You might consider paying the small additional cost for dedicated Hosting IP if:
You want to access your accounts by FTP as well as the Web when the domain name is otherwise inaccessible.
You want your site to be backwards-compatible with older browsers.
You want to create a corporate intranet.
You need a faster response with high traffic loads.
Prevent your emails being black listed as SPAM.
