As one of the previous responders noted, for some reason, today at least several hosts in 10.x.x.x zone had the reverse lookup set to show read-rfc1918-for-details.iana.net I had seen it myself for our regional router (or whatever it is) - today mid-day, then it turned back to be nameless again. It looks like somebody at IANA was tweaking (I hope not hacking :) the DNS for 10.0.0.1 or its part.
