gibt es eine möglcihkeit in c++
die ip zu ändern????

Welche? Die vom Mond?

Standard-C++ kennt weder Netzwerke noch IP-Adressen. Welches BS, welchen Compiler und welche Klassenbibliothek verwendest du?

WinAPI FORUM!!!

Ich habe letztens von nem Freund einer Bekannten gehört, dass es angeblich noch andere Betriebsysteme außer Windows geben soll

Aus diesem Grund werde ich mit dem Verschieben noch warten, trotz deines Gebrülls
