Lors du ping, les réponses ping proviennent de noms de domaine aléatoires, mais de la même adresse IP?

Lorsque je fais un ping sur un site, je reçois des réponses ping de domaines aléatoires. Vous pouvez le voir dans la pâte ci-dessous. J'ai commencé un ping, et j'ai surfé sur quelques sites, et le domaine ne cesse de changer.

J'ai également observé que mon Internet est lent à l'approche d'un nouveau site, mais une fois la page atteinte, il se charge rapidement et je peux généralement naviguer sur le site sans ralentissement. Je peux diffuser des films HD avec ma connexion (qui est une connexion DSL), donc la vitesse est là, mais il y a quelque chose de bizarre avec le DNS auquel je m'attends ?

Également intéressant, tous les ping rapportent environ 95 ms, mais les ping sont en fait assez sporadiques. Ce qui signifie que je vais m'asseoir pendant 10 secondes, puis 3 ou 4 pings reviendront très rapidement, puis il y aura une autre longue pause. Bien que certains pings prennent très clairement (par estimation visuelle) plus de temps que d'autres, ils rapportent tous le même temps de ping.

C'est mon premier post super utilisateur. J'espère que ce n'est pas trop spécifique, mais peut-être que cela peut aider quelqu'un d'autre. Sinon, je vais essayer un forum de support technique plutôt que les sites de FAQ d'échange de piles. (Cependant, j'ai trouvé une question similaire sur un site de FAQ similaire, mais je ne pouvais pas voir la réponse car je ne paierais pas. J'espère donc que les super utilisateurs me serviront mieux.)

PLUS D'INFOS :

• J'utilise Debian 6.
• Je suis câblé à mon routeur DSL.
• Un ordinateur portable Windows, connecté sans fil au routeur, n'a pas les mêmes problèmes, mais Windows fait probablement des pings différemment. Dans en particulier, j'ai remarqué que Windows ne signale pas le domaine dans son résultats du ping.
• Les résultats de ping ci-dessous proviennent de l'ordinateur avec le " problèmes de connexion."

/etc/resolv.conf est ci-dessous:
