Hallo,
ich habe ein programm geschrieben, mit welchem ich alle vergebenen IP-Adressen im Netzwerk auflisten will, was mir jedoch nur bedingt gelingt, unzwar gibt er erstens nicht wie gewünschte alle ping anfragen ein, dazu noch eine menge doppelt und nicht bis zum ende..
bin für jede Hilfe dankbar..
Code:
