Wie merkt Windows dass es Internet hat?

Beitragvon topas » 18.04.2017, 09:03

Weiss es jemand? Ich benötige für eine Bastelei mit Netzwerk die Möglichkeit festzustellen, ob das Netzwerk mit dem Internet verbunden ist. Windows "merkt" es ja sehr schnell, wenn das Internet weg ist. Aber wie macht es das?

Ob aus dem lokalen Netzwerk aus das Internet erreichbar ist, ermittelt man in dem man einen bekannten Server anpingt.

Bei Windows ist das dann natürlich ein extra dafür vorgesehener von Microsoft ;)
Wenn Du Wiresharks oder ähnliches benutzt, um den Traffic abzufangen, kannst Du das auch selbst beobachten. Unter Android habe ich das mal gemacht das war dann alle paar Minuten ein ping zu einem Google Server.

Danke für die prompten Antworten. Ja, der 2.Fall war gemeint. Also ist NCSI keine neue Krimiserie sondern ein Windows-Dienst. :D
