Since the app registers itself to receive notifications of changes in machine IP address, it is always current, and you can use it to know when you Mac is connected to the Internet by just looking at your menu bar. If it is not connected then the title will be empty: "-.-.-.-".
This app can also:
- Include machine name in menu bar
- Include wireless network name in menu bar
- Show the external Ip address in the menu
- Show more...
- Fixed a bug that could cause the app to quit when the option to display the wireless network name is selected in Preferences > Settings.
- OS X 10.6.6 or later
