In his study “THE IMPENDING IPv4 CRISIS: HOW U.S. COURTS ARE LIKELY TO APPROACH THE QUESTION OF OWNERSHIP RIGHTS IN IPv4 NUMBERS” Ernesto Rubi looks into claims whether IP addresses are given in ownership to the end-user. In short the answer is no. Here’s the link.
From what I’ve heard recently, the verdict in the California court case Kremen vs. ARIN substantiates this view. I’ll admit not to have found the actual text. If anyone has it, please send me a link and I’ll post it here also.
