Lots of network monitoring platforms use GeoIP databases to track/monitor sources. These databases are, perhaps, 75% accurate (for some definition of accurate).
This is your regular reminder to have a sense of caution about location based on public IP address.
John S. and his mother Ann live in the house, which is in Pretoria, the administrative capital of South Africa and next to Johannesburg. They had not abducted anyone, so they called the police and asked for an officer to come over. Roderick and the officer went through the home room by room, looking into cupboards and under beds for the missing girl. Roderick claimed to have used a “professional” tracking device “that could not be wrong,” but the girl wasn’t there.
This was not an unusual occurrence. John, 39, and Ann, 73, were accustomed to strangers turning up at their door accusing them of crimes; the visitors would usually pull up maps on their smartphones that pointed at John and Ann’s backyard as a hotbed of criminal activity.
