All devices on the World Wide Web are identified by a unique number called an IP address, for example 184.108.40.206. In case you have a site, the domain that you enter in order to access it is to save you time, yet the server where your site files are still has an IP address. Because there are far more websites and devices than there're IP addresses, all the shared web hosting servers have a number of websites under the very same IP, while when you use a dedicated server you'll get a dedicated IP too. Even in the first case though, you're able to obtain a dedicated IP for your websites and host them on a shared server. One benefit would be that you may have superior search engine rankings because a dedicated IP generally means a quicker loading website. Also, you need such an IP in case you plan to buy an SSL certificate for your site and protect the info that your visitors submit on it.
