IPv6 Security Issues by Samuel Sotillo on 08/11/06

For more than three decades now, the Internet’s endto- end model has functioned remarkably well. This model has allowed the evolution of a transparent network architecture that efficiently supports the transport of data without caring what the data it-self represents [7].

Unfortunately, the landscape is changing. Today, the Internet has grown to be a million-network network, which is something with startling consequences. For instance, one of the most publicized consequences of this growth has been the depletion of the Internet’s address space. Initially, the Internet’s address space consisted of 232 addresses—about 4 billion addresses.
