IP address geolocation

A new method for pinning down Internet clients to their geographic location was been developed by Yong Wang, a computer scientist at the University of Electronic Science and Technology of China.

Every computer is connecting to the Internet through a IP Address, but there is no simple way to map the IP Address to a physical location. Today’s best method of determining the geographic is able to pin down your location within a range of 35 km. Wang, on the other hand, is using a (pretty cool) algorithm(based on pinging known Google Maps landmark servers and comparing RTT) is able to determine your location within an average of 700 meters – and as close as 100 meters.


Even though Wang claims that this method will be helpful , to be honest, I see only bad things. This is a big the to the user’s privacy. I don’t want to Google or any other sites to know my physical location, unless I specifically say it.

And how about Lolita from Russia who is looking for a man from Denmark. Pretty soon she will start looking for a guy on my street. Not to mention spear-phishing.. I think those social engineers will be very happy to know the victim’s street address. My bet will be that they will sound more convincing.
