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 IP address of the target computer that runs the DHCP Server service.
-Confirm: Prompts you for confirmation before running the cmdlet.
-Description: Specifies a description of the multicast scope. The default value is null.
-EndRange (required): Specifies the end address of the range for the scope.
-ExpiryTime: Specifies the expiry time of the multicast scope. The default value is infinite.
-LeaseDuration: Specifies the duration of the IP address lease. The default value 30 days.
-Name (required): Specifies a name for the multicast scope.
-PassThru: Returns an object representing the item with which you are working. By default, this cmdlet does not generate any output.
-StartRange (required): Specifies the start address of the range of IP addresses for the scope.
-State: Specifies the state of the scope. The acceptable values for this parameter are: - Active - Inactive The default value is Active.
-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.
-Ttl: Specifies the number of routers through which multicast traffic passes. The default value is 32.
-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 an inactive multicast scope

Add-DhcpServerv4MulticastScope -ComputerName "DhcpServer01.Contoso.com" -Name "Multicast_AudioConference" -StartRange 224.0.0.0 -EndRange 224.0.0.30 -State Inactive -Ttl 20-LeaseDuration 20

This command creates an inactive multicast scope named Multicast_AudioConference on the DHCP server named DhcpServer01.Contoso.com. The command specifies the lease duration of 20 days for allocating addresses to participants of audio conferences. You can allocate a single multicast address to multiple clients. The command specifies that the traffic passes through 20 routers. Source: Microsoft, CC BY 4.0; transcript prompt/output removed. This example was not executed.
