These are the ports used or reserved by I2P, including those for known plugins, common alternates, and some typical related applications.
Note that many of these are not installed or enabled by default. There is more information in the FAQ. See also the documentation for individual plugins. Plugin authors please add any ports you use here. For new plugins, we recommend using the next available port in the 767x range.
