Just read this one on FourthAmendment.com:
“[N]o reasonable expectation of privacy exists in an IP address, because that information is also conveyed to and, indeed, from third parties, including ISPs. ‘IP addresses are not merely passively conveyed through third party equipment, but rather are voluntarily turned over in order to direct the third party’s servers.’” United States v. Christie, 2010 U.S. App. LEXIS 19285 (3d Cir. September 15, 2010) (unpublished)* [Yeah, like anyone knows any of this, that IP addresses are “voluntarily turned over.” Voluntary means you know what is being turned over. Pure fiction.]
To emulate the eminent privacy scholar W.C. Fields: “All things considered, I’d rather be in Switzerland.”
