    outerIP

    Acquires external IP address from command line

    Returns external IP address. That is all! Details: program is written in .net but can be used as library also. Executable available here is for winXP or higher. but you can convert it to c# <http://www.developerfusion.com/tools/convert/vb-to-csharp/> or run on linux using mono (it is tested for mono compilation here <http://www.tutorialspoint.com/compile_vb.net_online.php> and works fine) so it should work using mono on OSX also. You are welcome to contribute compiled executable for other OS' - to simplify process there is only one file required for compilation. Although this is simple program it includes all options for reliable acquiring external IP address, because it not depends on single server but many; use -? parameter for help or -?? for many additional options.
