Innate does not require a static IP address because all of your Innate data is actually stored in the cloud, as opposed to on a server in your office. The key advantage of a static IP address is that computers using this type of address can host servers containing data that other computers access through the Internet. A static IP address makes it easier for computers to locate the server.
