Detailed Description

The Remove-DhcpServerv4Reservation cmdlet deletes the IPv4 reservation from the specified scope. If the ScopeId parameter is specified, then all of the reservations from the scope are deleted. If the IPAddress or ClientId parameter is specified, then one or more specific reservations identified by IP addresses or client identifiers (IDs) are deleted.

Parameters

-AsJob

-CimSession<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.

-ClientId<String[]>

Specifies one or more client IDs for one of more reservations which are to be deleted. For Windows clients, the MAC address is used as a client identifier.

-ComputerName<String>

Specifies the DNS name, or IPv4 or IPv6 address, of the target computer running the Dynamic Host Configuration Protocol (DHCP) server service.

-IPAddress<IPAddress[]>

Specifies one or more IPv4 addresses for one or more reservations which are to be deleted.

-PassThru

Returns an object representing the item with which you are working. By default, this cmdlet does not generate any output.

-ScopeId<IPAddress>

Specifies the scope ID, in IPv4 address format, from which the reservations are to be deleted.

-ThrottleLimit<Int32>

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.

-Confirm

Prompts you for confirmation before running the cmdlet.

-WhatIf

Shows what would happen if the cmdlet runs. The cmdlet is not run.

<CommonParameters>

This cmdlet supports the common parameters: -Verbose, -Debug, -ErrorAction, -ErrorVariable, -OutBuffer, and -OutVariable. For more information, see    about_CommonParameters (https://go.microsoft.com/fwlink/p/?LinkID=113216).

Inputs

The input type is the type of the objects that you can pipe to the cmdlet.

• Microsoft.Management.Infrastructure.CimInstance#root/Microsoft/Windows/DHCP/DhcpServerv4Reservation

  The Microsoft.Management.Infrastructure.CimInstance object is a wrapper class that displays Windows Management Instrumentation (WMI) objects. The path after the pound sign (#) provides the namespace and class name for the underlying WMI object.

• Microsoft.Management.Infrastructure.CimInstance#root/Microsoft/Windows/DHCP/DhcpServerv4Scope

  The Microsoft.Management.Infrastructure.CimInstance object is a wrapper class that displays Windows Management Instrumentation (WMI) objects. The path after the pound sign (#) provides the namespace and class name for the underlying WMI object.

Outputs

The output type is the type of the objects that the cmdlet emits.

• Microsoft.Management.Infrastructure.CimInstance#root/Microsoft/Windows/DHCP/DhcpServerv4Reservation[]

  The Microsoft.Management.Infrastructure.CimInstance object is a wrapper class that displays Windows Management Instrumentation (WMI) objects. The path after the pound sign (#) provides the namespace and class name for the underlying WMI object.

Examples

EXAMPLE 1

This example deletes all of the reservations in the specified scope.

PS C:\> Remove-DhcpServerv4Reservation -ComputerName dhcpserver.contoso.com -ScopeId 10.10.10.0

EXAMPLE 2

This example deletes the specified reservations from the DHCP server service.

PS C:\> Remove-DhcpServerv4Reservation -ComputerName dhcpserver.contoso.com -IPAddress 10.10.10.5, 10.10.10.6

EXAMPLE 3

This example deletes the specified reservation identified by client ID from the DHCP server service. For Windows computers, the MAC address is used as a client identifier.

PS C:\> Remove-DhcpServerv4Reservation -ComputerName dhcpserver.contoso.com -ScopeId 10.10.10.0 -ClientId F0-DE-F1-7A-00-5E

EXAMPLE 4

This example deletes all of the reserved IP addresses from all of the scopes on the DHCP server service running on the computer named dhcpserver.contoso.com. The Get-DhcpServerv4Scope cmdlet returns all of the scope objects and pipes the objects into this cmdlet, which deletes the reservations from each of the scopes passed in through the pipeline.

PS C:\> Get-DhcpServerv4Scope -ComputerName dhcpserver.contoso.com | Remove-DhcpServerv4Reservation -ComputerName dhcpserver.contoso.com
