A dedicated IP address (also called static IP) means that a website has its IP address. Whether you type in your URL or the numeric form of its IP address, both will bring you to the same domain.
Who needs a dedicated IP address?
Having a website on a shared IP address will not cause you any harm. However, there are a few cases when a static IP is required…
- Having your Private SSL Certificate: Secure e-commerce websites need SSL certificates for accepting credit cards online. Web hosts usually offer a shared SSL certificate where clients can share the Web host’s SSL. If you are using your Web hosting provider’s shared SSL, you don’t need a static IP.
- Anonymous FTP: It means that anyone using the FTP software can access files in a special directory of your site. It’s called Anonymous FTP because the user name used to access is “anonymous.” Many Web hosting providers require a static IP for the anonymous FTP function to work properly.
- You want to access your website by FTP or Web browser even when the domain name is inaccessible, such as domain name propagation periods.
