Tracing Internet Protocol (IP) addresses

State v. Jacobs (Minn. Ct. App. April 17, 2007) 2007 Minn. App. Unpub. 360.

Tracing IP addresses back to a suspect using automated tools, even when the suspect is attempting hide himself, does not violate the suspect’s “reasonable expectation of privacy.”

U.S. v. Perez (5th Cir. April 11, 2007) 484 F.3d 735

Law enforcement obtained a search warrant based on the transmission of child pornography, which was traced back to a particular IP address registered to defendant.
