OK, they're pretty nebulous about the exact process, but you can piece it together. First we have this: * Stroz Friedberg has completed its initial review of MarkMonitor’s methodologies and found that the system is accurate and works properly. Importantly, the methodology for identifying infringed content and the IP address from which it has been distributed is based on a review of peer-to-peer networks and publicly available information.* So MarkMonitor is running a system that monitors p2p networks and collects IP addresses. And we have this: CCI has also retained Stroz Friedberg to review the technical processes used by each ISP to match subscriber accounts with IP addresses forwarded by the content owners. So content owners forward the IP addresses. You can't forward something you don't have. So clearly, MarkMonitor's system sends the IP addresses to the content owners, who can then do with them as they please. If you have some other information that contradicts what this article says, please do tell.
