Problema Quando creo un server minecraft....?

[ReBrnalJackson]

Allora ragazzi stavo creando un server minecraft vi spiego tutto:
inizialmente lo stavo creando con bukkit alla 1.8.1 ma il giorno dopo è stato aggiornato alla 1.0.0 ed ho lasciato perdere... però su hamachi mi rimane ancora l'ip con dei numeri (2620:9b::52d:dabd) .
io ho lasciato perdere... oggi stavo creando 1 server 1.0.0 e quando apro server con notepad c'è scritto
