Microsoft DnsServer reference: Adds a new delegated DNS zone to an existing zone. 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-DnsServerZoneDelegation. 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.
-ChildZoneName (required)
Specifies a name of the child zone.
-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 a DNS server. If you do not specify this parameter, the command runs on the local system. You can specify an IP address or any value that resolves to an IP address, such as a fully qualified domain name (FQDN), host name, or NETBIOS name.
-Confirm
Prompts you for confirmation before running the cmdlet.
-IPAddress (required)
Specifies an array of IP addresses for DNS servers for the child zone.
-InputObject (required)
Specifies the input to this cmdlet. You can use this parameter, or you can pipe the input to this cmdlet.
-Name (required)
Specifies the name of the parent zone. The child zone is part of this zone.
-NameServer (required)
Specifies the name of the DNS server that hosts the child zone.
-PassThru
Returns an object representing the item with which you are working. By default, this cmdlet does not generate any output.
-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.
-VirtualizationInstance
Specifies the virtualization instance in which the zone will be added. A virtualization instance is logical partition in a DNS Server, which is capable of independently hosting zones and zone scopes. Same name zones and zone scopes can be hosted in different virtualization instances. This parameter is optional and if not provided it will add the zone into the default virtualization instance which is functionally equivalent to a standard DNS server.
-WhatIf
Shows what would happen if the cmdlet runs. The cmdlet is not run.
-ZoneScope
Specifies the name of a zone scope. If you do not specify this parameter, the cmdlet adds the delegation into the default scope of the zone. We recommend that you add the delegations in all available scopes. Not adding delegations in all scopes causes loss in visibility to the child domains by means of certain scopes of parent zone where you do not add delegation.
Prerequisites
Windows with the DnsServer 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.
This command creates a delegation for west01 in the zone contoso.com with the specified name server and IP address. Source: Microsoft, CC BY 4.0; transcript prompt/output removed. This example was not executed.
