A dedicated IP address means that you will have a unique numeric identifier on the Internet and that it shall not be shared with other's websites or applications as it happens with a shared hosting account. There are lots of uses for a dedicated IP - including, when an SSL certificate is required if you have a web-based store and you want to accept online payments or if you have a login form and you would like the data that users submit to be encrypted. A dedicated IP address could also be used for other apps, like a VoIP server, for instance. Moreover, it will give more credibility and security to your sites, given that a network flood to a shared IP won't have any effect on your dedicated IP. If you host your websites with us and you have your own hosting server, you will be able to get one or numerous dedicated IP addresses with only a couple of clicks and to use them in the event that you cannot use the IP that comes with the server.
