But this changed when Microsoft added IPv6 support to its Windows Vista and Windows Server platforms in 2007. Linux in all its variants and Apple’s Mac OS X followed suit; thus, the new protocol spread with each new installation. On all of these computers today, IPv6 is active by default, communicating in unsolicited dual-stack operations using IPv4 and IPv6. Moreover, Microsoft’s operating systems introduced transition technologies, which use IPv4 as a link-layer protocol for IPv6 use. This happens autonomously and, in some cases, long before admins organize normal IPv6 operations – which is exactly where the latent threat lies.

IPv6 is enabled and active by default, and the systems on the networ...
