No problem, thanks for trying - I still dont believe its DNS though, i've also 
just tried the command substituting the DNS names with IP addresses and 
although this just says there are no matches, including the volume in the query 
still gives the DNS name querying stuff, where as leaving it out, just simply 
says no matches found.
