If you have advanced hosting needs, Dedicated Hosting IP (Internet
Protocol) may be for you. A Dedicated Hosting IP means each web
hosting account has a unique address, not shared by any other accounts
on the same server.
Overview Since the majority of sites on the Web are hosted via shared IP,
most X n Y n Z hosting customers don't need a Dedicated Hosting IP.
However, 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, such as domain name propagation periods.
You want your site to be backwards-compatible with older browsers.
