Almost certainly not. It's very likely your network provider or one of 
their upstreams put this block in, in response to a reflection attack; 
many attackers sems to use queries for (and others) for some reason.

Ask your provider what they've done, and to exclude you from it (better 
yet, fix their broken filter)
