The Dynksys Dynamic IP Updater is a Java-based application that will determine your network's external IP address and update it to a dynamic host name service such as dhs.org or DynDNS.org. It includes a Java Swing GUI that lets you enter all the configuration information, and a Java runtime that can be installed to Windows as an NT Service or run from the command line. The runtime checks your external IP address and determines if it's up to date. If it's not it will update your external IP address to the dynamic host service. Take a look at the User Guide for more information on how it can be installed, configured, etc.
