[Linux] Décryptage requête whois

[François DREYFÜRST]

Bonjour à tous

De temsp en temps, mon firewall (toujours lui ...) l'indique un « hit » 
(tentative de connexion qu'il a bloquée, souvent alors que j'étais en 
train de naviguer sereinement) en provenance de « kundenserver.de », le 
truc curieux étant que je n'étais absolument pas sur des sites allemands ...
Je vous ai copié ce que me renvoie un whois sur ce nom, en annexe ; 
quelqu'un peut-il me dire s'il y a quelque chose de louche ?

Merci
FD
