My answer is that it depends. The basic subscriber information that would be given in exchange, for example, for a listed phone number is the kind of information that you would expect to find in a phone book and that individuals generally expect to be publicly available. When you have a request that's made by law enforcement to an Internet service provider, a telecom company, and the seed of the request is an IP address, an Internet protocol address, then you're asking for subscriber information. In my view, that reveals more than what's publicly available. That reveals the places that you're going on the Internet, the sites that you're visiting.
