An Internet Protocol (IP) address is a numerical label that is assigned to devices participating in a computer network. An IP address serves two principal functions in networking: host or network interface identification and location addressing. The role of the IP address has also been characterized as follows: "A name indicates what we seek. An address indicates where it is."
By default, your hosting account and all the websites you have with us use the shared IP address of the server - meaning that many websites on the same server reside under the same IP address. You have the option to use a dedicated IP address and your domain or subdomain will be the only one corresponding to this IP address. In other words, the dedicated IP address will be reserved just for you not only on our server and network but worldwide on the Internet.
One of the main uses of dedicated IP addresses concerns the installation of SSL certificates that are required for secure pages. If you wish to have a form on the website that will collect sensitive information, for example, for payments or client accounts, it is advised to have that page secured in order to protect the personal or financial information of your visitors and clients.
Another purpose of using a dedicated IP address is if you need to open your website using the IP address as a URL instead of using the domain or subdomain it is hosted under.
