Using the network properties GUI to disable IPv6 is not supported Settingĭisable IPv6 on nontunnel interfaces (except the loopback) and on IPv6 tunnel interface Refer to the following table for an example.

Windows use bitmasks to check the DisabledComponents values and determine whether a component should be disabled.
Replace the with the corresponding value. Run the following command: reg add "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip6\Parameters" /v DisabledComponents /t REG_DWORD /d /f Open an administrative Command Prompt window. You can also follow these steps to modify the registry key: If this behavior isn't desired, we recommend disabling the IPv6 tunnel interfaces on the affected hosts. 6to4 automatically assigns an IPv6 address to the 6to4 tunneling interface for each address, and 6to4 dynamically registers these IPv6 addresses on the assigned DNS server. Values other than 0 or 32 causes the Routing and Remote Access service to fail after this change takes effect.īy default, the 6to4 tunneling protocol is enabled in Windows when an interface is assigned a public IPv4 address (Public IPv4 address means any IPv4 address that isn't in the ranges 10.0.0.0/8, 172.16.0.0/12, or 192.168.0.0/16).You must restart your computer for these changes to take effect.admx file to expose the registry settings of below table in a Group Policy setting.

You cannot completely disable IPv6 as IPv6 is used internally on the system for many TCPIP tasks. Even if the DisabledComponents registry key is set to disable IPv6, the check box in the Networking tab for each interface can be checked.
The DisabledComponents registry value doesn't affect the state of the check box. For more information, see Internet Protocol Version 6 (IPv6) Overview. Additionally, system startup will be delayed for five seconds if IPv6 is disabled by incorrectly, setting the DisabledComponents registry setting to a value of 0xffffffff.

The IPv6 functionality can be configured by modifying the following registry key: Before you modify it, back up the registry for restoration in case problems occur. Serious problems might occur if you modify the registry incorrectly. Follow the steps in this section carefully.
