I have created an application to help with automatic network configuration for the different tasks required in FRC. This project is still in a very early release state so there are plenty of "undocumented features", i.e. bugs I'm sure.
The project is hosted on google code at:
http://code.google.com/p/frc-network-tool/
If you wish to aid in development please PM me.
This tool was developed for the following reasons:
-Help provide new teams information for network configuration
-Help provide a more seamless operation during robot testing
-Help provide a better mechanism for network configuration for teams that have a complex network environment at their development location.
