ip address tracking
 

so im trying to track a ip address to a specific location, all the free location searches i can find just tell you where the building that the service provider is located at.
anyone have a idea?
also i found a web program that tells you if the e mail you sent is opened, for how long, and the recievers ip address , if anyone wants the website let me know its a 10 day 30 e mail free trial
