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.
