Microsoft DhcpServer reference: Adds an IPv6 scope to the DHCP server service with the specified parameters. 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 Add-DhcpServerv6Scope. 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. The cmdlet immediately returns an object that represents the job and then displays the command prompt. You can continue to work in the session while the job completes. To manage the job, use the *-Job cmdlets. To get the job results, use the Receive-Job cmdlet. For more information about Windows PowerShell® background jobs, see about_Jobs.
-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.
-ComputerName
Specifies the DNS name, or IPv4 or IPv6 address, of the target computer that runs the DHCP server service.
-Confirm
Prompts you for confirmation before running the cmdlet.
-Description
Specifies the description associated with the scope.
-Name (required)
Specifies the name associated with the scope.
-PassThru
Returns an object representing the item with which you are working. By default, this cmdlet does not generate any output.
-Preference
Specifies the value for the preference field to be used by the DHCP server service while responding to clients in this subnet. The acceptable values for this parameter are: 0 through 255. The default value is 0.
-PreferredLifetime
Specifies the preferred life time of the IPv6 address leased by the DHCP server service. The default value is 8 days. This parameter value should be same or less than the *ValidLifeTime* parameter value.
-Prefix (required)
Specifies the IPv6 prefix of the scope that is added.
-State
Specifies the state of the scope. The acceptable values for this parameter are: Enabled and Disabled.
-T1
Specifies the lease renewal time. The default value is 4 days. The DHCP client is expected to use a unicast message to renew the lease at the time specified by this parameter value from the same DHCP server service from which DHCP client had at first obtained the lease. This parameter value should be less than the *T2* and *PreferredLifetime* parameter values.
-T2
Specifies the lease rebind time. The default value is 6.4 days. The DHCP client is expected to use a multi-cast message to renew the lease at the time equal to this parameter value from any DHCP server service if the renewal attempt at time specified by the *T1* parameter fails. This parameter value should be larger than the *T1* parameter value and less than the *PreferredLifetime* parameter value.
-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.
-ValidLifeTime
Specifies the valid life time of the IPv6 address leased by the DHCP server service. The default value is 12 days. This parameter value should be same or larger than the *PreferredLifetime* parameter value.
-WhatIf
Shows what would happen if the cmdlet runs. The cmdlet is not run.
Prerequisites
Windows with the DhcpServer 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.
Examples
Example 1: Add a server scope on the local computer
The above command adds a DHCPv6 scope with subnet prefix 2001:4898:7020:1020:: and specified scope name to the DHCP server that runs on the local computer. Source: Microsoft, CC BY 4.0; transcript prompt/output removed. This example was not executed.
