Cox Communications, Inc. v. Sony Music Entertainment · ¶18

Internet service providers, such as Cox, have limited knowledge about how their Internet services are used and who uses them. They do know which IP address corresponds to which subscriber's account, but they cannot distinguish one individual user from another. For instance, if an Internet service provider learns that someone illegally downloaded music from a coffee shop's IP address, the Internet service provider cannot determine which individual at the coffee shop infringed the copyright. And, more generally, Internet service providers also cannot directly control how their Internet services are used.
