On February 3, 2011 the current version of the Internet IPv4 was depleted of addresses. Since the Internet today uses IPv4 for 99% of the traffic, it will be a slow migration to IPv6.1.The shortage of addresses has led to the introduction of IPv6 which has 128-bit (16-byte) source and destination IP addresses. Many organizations do not see a reason to convert to IPv6 and believe they are not running IPv6.2 whether an organization knows it or not, any laptop/PC running Vista or Windows 7 is a vulnerability from which attacks can come that will be invisible to IPv4 networks.
