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.

Delete Autoconfigured IPv6 address

C:\><input>netsh interface ipv6 delete address 12 2001:16d8:dd85:a200:221:86ff:fea0:ce84</input>

Prefer IPv4 instead of IPv6

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.

C:\><input>netsh interface ipv6 add prefixpolicy 2001:470::/32 3 6</input>
C:\><input>netsh interface ipv6 show prefixpolicies</input>
