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.
