hab seit vorgestern ein ziemliches Problem mit der Namensauflösung.
Und zwar dauert sie entweder zu lange (viiiel zu lange), oder liefert kein Ergebnis.

gregor@elch:~$ host www.tagesschau.de

Ich wüsste absolut nicht, woran es liegen könnte. Einfach mal so hab ich eine Probeanfrage gestartet und den Netzwerkverkehr per Ethereal mitgeloggt:

Wie die ganze Geschichte entstanden ist, weiß ich nicht. Hab nichts verändert (zumindest nicht wissentlich).
Schonmal danke im Voraus.
//edit :: glaub ich hatte mir mal angewöhnt, quote zu verwenden, weil (hier) code dazu geführt hat, dass es schlechter lesbar ist.. groß + kursiv wenn ich mich nicht irre. da sich das inzwischen geändert hat.. ok
