I have my own IP range and the data is accurate to the meter, which is what worries me.
For example, we know where our ProbeNet PoPs are located. If hops to your ranges are through private IPs or sub 1 MS RTT, we can pretty much confidently tell the name of the data center. However, considering that there are data centers that span thousands of square meters, we can point to the data center building, rather than the rack or the room.
To me, it is likely a coincidence.
