IPv6 

Currently there is no support for IP version 6 within the network or on any CIS supported host. In addition badly configured systems with IPv6 can have a negative impact on the network, sometimes tantamount to a denial-of-service attack. Consequently we require attached devices to the network to ensure IPv6 is disabled within their network settings.

 On a Windows PC, there is a quick way to ensure this by making the following registry setting

 [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip6\Parameters]

"DisabledComponents"=dword:000000ff

 followed by a re-boot of the system.

Alternately, perform the following commands to disable 6to4, Teredo and ISATAP:

netsh int ipv6 6to4 set state disabled
netsh int ipv6 set teredo disable
netsh int ipv6 isatap set state disabled
