Cox Communications, Inc. v. Sony Music Entertainment · ¶80

This problem is even more glaring when it comes to connections that serve hundreds or thousands of users. For instance, Cox provides internet service to regional ISPs who in turn supply internet service to thousands of users. Given the numbers involved, it is hardly surprising that Cox has received many copyright-violation notices as to connections supplied to regional ISPs. Still, Cox does not know who among a regional ISP's thousands of customers is committing infringement, even if it knows that someone has infringed in the past and that someone will infringe in the future.
