DDNS Updater

DDNS Updater checks for changes to the external IP address of a Microsoft Windows computer, and updates a dynamic DNS (DDNS) service whenever a change is detected. DDNS Updater has the following features: * Compatible with a large number of DDNS services, thanks to a configurable HTTP API. * Minimizes API calls, for instance, by persistent caching of the IP address and local IP matching. * Configurable check and update intervals. * Works with IPv4 and IPv6 (including dual-stack). * Sends email when the detected IP address changes. * Runs as a Windows service, so that updating occurs even when no-one is logged in. * Completely free of charge with no adware or spyware. * No transmission/collection of data.
