- Todos los puertos por debajo de 9000 (excepto 8887) se vinculan a 127.0.0.1 por defecto por seguridad.
- El puerto de red del router (9151–30777) debe estar abierto a internet para participación completa.
- i2pd utiliza principalmente las mismas asignaciones por compatibilidad (7070 consola, 7654 I2CP, 7656/7655 SAM).
- Los desarrolladores de plugins deben coordinar nuevas asignaciones a través de la comunidad I2P para evitar conflictos.
