Brian Lich|Last Updated: 3/27/2017

SYNOPSIS

Deletes the IPv4 reservation from the specified scope.

SYNTAX

IPAddress (Default)

Remove-DhcpServerv4Reservation [-ComputerName <String>] [-PassThru] -IPAddress <IPAddress[]>
 [-CimSession <CimSession[]>] [-ThrottleLimit <Int32>] [-AsJob] [-WhatIf] [-Confirm] [<CommonParameters>]

ScopeId

Remove-DhcpServerv4Reservation [-ScopeId] <IPAddress> [-ComputerName <String>] [-PassThru]
 [-CimSession <CimSession[]>] [-ThrottleLimit <Int32>] [-AsJob] [-WhatIf] [-Confirm] [<CommonParameters>]

ClientId

Remove-DhcpServerv4Reservation [-ScopeId] <IPAddress> [-ClientId] <String[]> [-ComputerName <String>]
 [-PassThru] [-CimSession <CimSession[]>] [-ThrottleLimit <Int32>] [-AsJob] [-WhatIf] [-Confirm]
 [<CommonParameters>]

DESCRIPTION

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

EXAMPLES

Example 1: Delete all reservations in a scope

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

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

Example 2: Delete specified reservations

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

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

Example 3: Delete reservations for a specified client

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

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

Example 4: Delete reserved IP addresses from all scopes

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

This example deletes all of the reserved IP addresses from all of the scopes on the DHCP server service that runs 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 scope passed in through the pipeline.

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.

Type: SwitchParameter
Parameter Sets: (All)
Aliases: 

Required: False
Position: Named
Default value: None
Accept pipeline input: False
Accept wildcard characters: False

-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.

Type: CimSession[]
Parameter Sets: (All)
Aliases: Session

Required: False
Position: Named
Default value: None
Accept pipeline input: False
Accept wildcard characters: False

-ClientId

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

Type: String[]
Parameter Sets: ClientId
Aliases: 

Required: True
Position: 2
Default value: None
Accept pipeline input: True (ByPropertyName)
Accept wildcard characters: False

-ComputerName

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

Type: String
Parameter Sets: (All)
Aliases: Cn, ReservationServer

Required: False
Position: Named
Default value: None
Accept pipeline input: False
Accept wildcard characters: False

-Confirm

Prompts you for confirmation before running the cmdlet.

Type: SwitchParameter
Parameter Sets: (All)
Aliases: cf

Required: False
Position: Named
Default value: False
Accept pipeline input: False
Accept wildcard characters: False

-IPAddress

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

Type: IPAddress[]
Parameter Sets: IPAddress
Aliases: ReservedIP

Required: True
Position: Named
Default value: None
Accept pipeline input: True (ByPropertyName)
Accept wildcard characters: False

-PassThru

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

Type: SwitchParameter
Parameter Sets: (All)
Aliases: 

Required: False
Position: Named
Default value: None
Accept pipeline input: False
Accept wildcard characters: False

-ScopeId

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

Type: IPAddress
Parameter Sets: ScopeId, ClientId
Aliases: ReservationScopeID

Required: True
Position: 1
Default value: None
Accept pipeline input: True (ByPropertyName)
Accept wildcard characters: False

-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.

Type: Int32
Parameter Sets: (All)
Aliases: 

Required: False
Position: Named
Default value: None
Accept pipeline input: False
