PMI’s Revolution can be configured to use a cellular modem as one of its many different means of connectivity. When this option is present the modem can be configured in one of two ways: with a static IPv4 address or with a dynamic IPv4 address. A static IP address is always the same, and thus easy to program into ProVision for connection. A dynamic IP address may change at any time, presenting a difficulty for establishing an outside connection. To keep track of dynamic IP addresses, PMI hosts a service that logs the most recent address of each Revolution, and ProVision queries this log to connect to a specific Revolution. This system is described in this paper.
The latest version of the IP Address Resolution Service provides an increase in security, stability and ease of use. By upgrading ProVision and the Revolution firmware, the user can take advantage of these new features and enable connection to cell Revolutions with dynamic IP address.
