Right, and my point is that you essentially can't. For my address the best you could do is narrow it down to ~30 or so homes that share the same first digit as my address. For this to work you have to:
(1) Have the IP address return the right location
(2) Not have duplicate street names in that location
(3) Have a single digit address OR be the only home starting with that number
That's going to be a pretty rare combo. Probably less than 1%.
They'll be able to narrow it down to 10-30 homes, but from there they can see who owns those homes, research those people on social media etc., and determine who their likely target is.
