#Description:
#
#Dieses Script ist in der Lage, mit einer grafischen
#Oberfläche Hosts zu pingen und ihre Domain/Hostnamen in IP&´s
#aufzulösen und umgekehrt. Ich habe es bisher nur unter Windows
#getestet. Es ist allerdings Plattformunaghängig programmiert.
#Sollte also auch auf Linux laufen.
#
#
#
#Dieses script kann frei genutzt und verbreitet werden.
