Subject: Unusual DNS requests (not related to previous DNS thread) So far, so good. The request is for a PTR record: 0.xxx.xxx.xx.in-addr.arpa. No, that's not a typo, they are requesting reverse for the network address at .0. A packet capture shows absolutely nothing out of the ordinary, other than the freaky request, and the regularity of the requests, about one request every five seconds, round the clock.
It's not unusual at all. Please read RFC 1101. -- Greg A.
