The current version of the internet, IPV4 was depleted of addresses on february3, 2011. The storage of address has led to the introduction of IPV6 which has 128-bit (16-byte) source and destination IP addresses. Many organisations do not see a reason to convert to IPV6, and believe they are not running IPV6.Whether an organisation 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. Since the Internet today uses IPV4 for 99% of the traffic, it will be slow migrations to IPV6.
