How do they keep track of people like me who have dynamic IP addresses? 
  And, for that matter, I'm house sitting right now over fifty miles 
from home using a friend's connection.  How can they tell that my DNS 
queries are mine, not his?  (Not that I use Google's DNS, but the 
question's still valid in the general case.)
