A dedicated IP address ensures that you will have a unique numeric identifier on the Internet and that it will not be shared with other people's sites or applications as it happens with a shared hosting account. There are lots of uses for a dedicated IP - for instance, when an SSL certificate is needed if you have an electronic store and you need to accept online payments or in the event that you have a login form and you would like the data which users submit to be encrypted. A dedicated IP address could also be used for other apps, like a VoIP server, for example. Moreover, it shall give more credibility and security to your sites, given that a network flood to a shared IP shall not have any impact on your dedicated IP. If you host your sites with us and you have your own hosting server, you'll be able to get one or numerous dedicated IP addresses with simply a couple of clicks and to use them just in case you cannot use the IP included with the web server.
