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.C:\><input>netsh interface ipv6 show addresses</input>

Disable IPv6 using 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.
Prefer IPv4 over IPv6 using Hurricane Electric
Low precedence on IPv6
Hurricane electric use the 2001:470::/32 prefix. (Look at your IPv6 address and adjust as needed). In the command it's given a very low precedence - 3.
