TrueIP is a small and very simple tool that allows you to monitor your computer's IP address and, if you change it, perform various actions (sending a notification or launching an executable file). After launching, the program is available as a small icon within the system tray, from where it provides the user with information about the current local and external IP address of the computer and the host name. TrueIP also allows you to record this data and save it as a log file on your hard drive and define how often you want to check it.

Going further, TrueIP allows you to perform many useful actions when you detect a change in your computer's IP address. In addition to the basic notification via a small window, the program also offers notifications via e-mail, FTP or the option to run any external application. The tool supports multiple Dynamic DNS providers, allowing you to automate DNS record update operations after a change of IP address.
