Microsoft NetworkTransition reference: Sets the 6to4 configuration for both client computers and servers. The syntax and selected example below are adapted from the pinned Windows Server 2025 reference. Module availability, target configuration and delegated permissions determine whether it can run in your environment. Documentation and parameter text: Microsoft, CC BY 4.0; formatting adapted by Cmdlet World. No execution testing is claimed.
Use an account with the target resource permissions documented for Set-Net6to4Configuration. Modifying administrative cmdlets may require elevation or delegated administration. This catalog does not assert that ordinary users can execute the command.

Parameters
-AsJob
Runs the cmdlet as a background job. Use this parameter to run commands that take a long time to complete.
-AutoSharing
Determines if 6to4 prefixes are forwarded when Internet Connection Sharing (ICS) is enabled. By default, 6to4 prefixes are forwarded.
-CimSession
Runs the cmdlet in a remote session or on a remote computer. Enter a computer name or a session object, such as the output of a New-CimSession or Get-CimSession cmdlet. The default is the current session on the local computer.
-Confirm
Prompts you for confirmation before running the cmdlet.
-GPOSession
Specifies the Group Policy session in which to store the 6to4 configuration information. You can use this parameter with the NetGPO cmdlets to aggregate multiple operations performed on a Group Policy Object (GPO). You cannot use this parameter with the *PolicyStore* parameter.
-IPInterface
Specifies the IP interface on which to set the 6to4 configuration.
-InputObject (required)
Specifies the input object that is used in a pipeline command.
-PassThru
Returns an object representing the item with which you are working. By default, this cmdlet does not generate any output.
-PolicyStore
Specifies the policy store that contains the configuration to set. The acceptable values for this parameter are: - PersistentStore - ActiveStore - GPO To set the configuration of a GPO, specify the GPO name using the following format: Domain\GPOName You cannot use this parameter with the *GPOSession* parameter.
-RelayName
Specifies a 6to4 relay name. If 6to4 connectivity is not available on the computer, the relay name setting has no effect.
-RelayState
Configures the 6to4 relay state. The acceptable values for this parameter are: - Default. If the host has link-local only IPv6 connectivity and a public IPv4 address, then 6to4 is enabled. If there is no global IPv6 address present and no global IPv4 address present, then the host does not have a 6to4 interface. If there is no global IPv6 address present but there is a global IPv4 address present, then the host has a 6to4 interface. - Enabled. If there is a global IPv4 address present, then the host has a 6to4 interface. If there is no global IPv4 address present, then the host does not have a 6to4 interface. - Disabled. 6to4 is turned off and connectivity with 6to4 is not available. - Automatic.
-ResolutionIntervalSeconds
Specifies the frequency for resolving the relay name. The 6to4 relay name resolution interval setting has no effect if there is no 6to4 connectivity available on the host.
-State
Specifies the state behavior of 6to4. The acceptable values for this parameter are: - Default. If the host has link-local only IPv6 connectivity and a public IPv4 address, then 6to4 is enabled. If there is no global IPv6 address present and no global IPv4 address present, then the host does not have a 6to4 interface. If there is no global IPv6 address present but there is a global IPv4 address present, then the host has a 6to4 interface. - Enabled. If there is a global IPv4 address present, then the host has a 6to4 interface. If there is no global IPv4 address present, then the host does not have a 6to4 interface. - Disabled. 6to4 is turned off and connectivity with 6to4 is not available. - Automatic.
-ThrottleLimit
Specifies the maximum number of concurrent operations that can be established to run the cmdlet. If this parameter is omitted or a value of 0 is entered, then Windows PowerShell® calculates an optimum throttle limit for the cmdlet based on the number of CIM cmdlets that are running on the computer. The throttle limit applies only to the current cmdlet, not to the session or to the computer.
-WhatIf
Shows what would happen if the cmdlet runs. The cmdlet is not run.
Prerequisites
Windows with the NetworkTransition module and the Windows feature or management tools that provide it. Confirm target connectivity and version compatibility using the linked Microsoft reference.
Security considerations
This cmdlet changes system state. Review every target and parameter in the official reference, test outside production, and prepare an appropriate backup or rollback. Do not execute the example automatically.
