I'm not sure if these are _only_ related to Qhosts but I have found a 
number of IP's in people's hostfiles and DNS settings in much the same 
style as qhosts.  I've included the ones I've seen below.

In hosts files:
64.191.59.85
207.44.194.56
64.191.95.139
205.134.176.246

In DNS settings:
207.44.220.30
69.57.146.14
69.57.147.175
216.127.92.38

Its easy to make snort rules for these to find infected computers.
