Zone or Ifindex

The IPv6 Link-Local Address is local on the link (interface) and the node has several links (interfaces) - all with the same IPv6 Link-Local prefix. Because of this it's necessary to identify the Link in question. For example the Link-Local address from below fe80::221:86ff:fea0:ce84%12 where fe80::221:86ff:fea0:ce84 is the address and %12 is the Zone identifier which identifies the Link. In this case interface 12 is the "Local Area Connection". Which is my Ethernet adapter.

Regedit

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip6\Parameters\DisabledComponents

  • Note If the DisabledComponents entry is unavailable, you must create it. (32 bit DWORD)
  • 0x0 to enable all IPv6 components.
    • Note The value "0" is the default setting.
  • 0xffffffff to disable all IPv6 components, except the IPv6 loopback interface. This value also configures Windows Vista to use Internet Protocol version 4 (IPv4) instead of IPv6 in prefix policies.
  • 0x20 to use IPv4 instead of IPv6 in prefix policies.
  • 0x10 to disable native IPv6 interfaces.
  • 0x01 to disable all tunnel IPv6 interfaces.
  • 0x11 to disable all IPv6 interfaces except for the IPv6 loopback interface.
