"There are just 4 billion possible IP addresses if we do not move from version 4 of the Internet Protocol to version 6. After the move, there would be 340 trillion trillion trillion (3.4 x 10**36) possible addresses under v6, because of the 128-bit address space. Scalability is just one reason to make the move, but the new levels of security that could be achieved - quite apart from much better network management, especially for mobile devices - make the move highly desirable."
"A further benefit of switching to IPv6 would be to get better and more reliable performance."
