Detecting IPv6 Tunnels in an Enterprise Network

The ongoing depletion of unique and global IPv4 addresses is creating an increased focus on IPv6 technology. The regional registries run ongoing statistics on the available IPv4 address pool and realize that they will be unable to meet IPv4 address block requests at some point in the future. Most major computer operating system vendors support IPv6 and have it enabled by default. They will even try to use IPv6 through dynamic tunneling technologies if the enterprise network is capable of supporting IPv4 only. An important consideration is that IPv6 is quite likely to be already running on the enterprise network, whether that implementation was planned or not.
