Current Version: 3.0 (November 8, 2003) / 3.1.5 (March 31, 2010)

Similar to DynDNS Updater, but working in conjunction with the No-IP system at, No-IP allows your computer to have a consistent domain name every time you connect to your ISP.

No-IP includes two components:

  • Update Client (Installed into: /Applications) - This graphical application is used to perform instant and scheduled updates to your No-IP hosts. It is also used to configure the UNIX Background Daemon.
  • UNIX Background Daemon (Installed at: /usr/local/bin/noip2) - This faceless program can be configured to run in the background as a system service. It will automatically update the No-IP servers whenever your IP address changes.

Unlike DynDNS Updater, No-IP is not a Universal Binary, but it is available for "Classic" Mac OS.

While no information is available regarding what's new in version 3.1.5, version 3.1.3b3 made the following enhancements:

  • Improved Daemon Functionality
  • Standardized Drag and Drop Installer
  • Utilizes New Logos
  • And More

These are applications that are newer and of potential interest, but which I haven't yet selected for permanent inclusion. Have a look, and let me know if you think they deserve to be part of the permanent collection!
