Determination of IP address location?
How have others found determining the IP address location to be objectively determined? I am aware for forensic purposes the MAC address is usually needed, however, given that sometimes the MAC address is not ascertained, is there a way the IP address may provide information regarding the location? Also, considering the cyber criminal usually changes IP addresses constantly, is there a way of tracing the different IP addresses a cyber criminal may use to one location of origination?
"Location" meaning physical location?
