DynDNS Updater is a small tool designed to monitor changes in the computer's IP address and automatically update data stored in one of the popular DDNS services. The program is supported by the settings wizard, which guides us step by step through the initial configuration process. The user is provided with the functions of automatic IP address detection, informing by e-mail about a change of the current IP address (SMTP authentication and SSL connection support), support for modification of multiple hosts during a single data update, as well as logging of all relevant logs.

DynDNS Updater supports standard wired, modem, ADSL and many more. The tool can be run together with the operating system or installed in it as a service.
