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

I had seen it myself for our regional router (or whatever it is) -

It looks like somebody at IANA was tweaking (I hope not hacking :) 
the DNS for or its part.
