- Tous les ports en dessous de 9000 (sauf 8887) se lient à 127.0.0.1 par défaut pour la sécurité.
- Le port réseau du router (9151–30777) doit être ouvert sur internet pour une participation complète.
- i2pd utilise principalement les mêmes attributions pour la compatibilité (7070 console, 7654 I2CP, 7656/7655 SAM).
- Les développeurs de plugins devraient coordonner les nouvelles attributions via la communauté I2P pour éviter les conflits.
