Lemmee see, the issue is, whose barn do we burn down, based on the 
telephone number associated with it--the one the with the switch or the 
one with the telephone?

There right answer is predicated on the the facts that the number (IP or 
telephone or serial number plate) is of NO use what ever in locating 
anything, certainly not as a cause for action.  Anybody who acts 
different;y should have painful things done to them.

I don't care what expert tells you different.

A case in point--the other day I had need for the ZIP code for the house 
I lived in at age 10.  So I Binged the address for a ZIP code and got 
one.  Along with a Googlish picture that goes with the address.

When I was 10, the address was for one of four tiny houses on a small 
city lot.  (Which, I discovered in later years was in a barrio, and 
populated by people at of below the poverty line, if anybody had used 
that terminology then.)

The picture was of a KITCHEN! that appeared to be bigger than the house 
I lived in--the Zillow entry for the property now was 3/4 of a million 

Knowing the address of a place is not definitive of the place.  Period.
