Oh, you wanted me to say that 90% of the IPs I'm 
trying to resolve actually are resolvable on 
other hosts, but I get this error on my box? I 
"obscured" that IP (I didn't obscure anything, I 
just used x.x.x.x as a "wildcard" for all the 
queries that are failing), because I fail to see 
the relevance of quoting a single IP out of 
thousands that is resolvable on your host, but 
fails to resolve on mine. These IPs are from all 
over the world, on practically every ISP 
imaginable. Now for all of you who think I'm 
wrong in assuming this, here is one of the IPs in 
question: Any help would be greatly appreciated.
