Remove-DhcpServerv6Reservation

Brian Lich|Last Updated: 3/27/2017

SYNOPSIS

Deletes IPv6 reservations from the specified scope.

SYNTAX

IPAddress (Default)

Remove-DhcpServerv6Reservation [-ComputerName <String>] -IPAddress <IPAddress[]> [-PassThru]
 [-CimSession <CimSession[]>] [-ThrottleLimit <Int32>] [-AsJob] [-WhatIf] [-Confirm] [<CommonParameters>]

Prefix

Remove-DhcpServerv6Reservation [-ComputerName <String>] [-PassThru] [-Prefix] <IPAddress>
 [-CimSession <CimSession[]>] [-ThrottleLimit <Int32>] [-AsJob] [-WhatIf] [-Confirm] [<CommonParameters>]

DESCRIPTION

The Remove-DhcpServerv6Reservation cmdlet deletes one or more IPv6 reservations from the specified scope. If you specify the Prefix parameter, all of the reservations from the scope are removed. If you specify the IPAddress parameter, one or more specified reservations are removed.

EXAMPLES

Example 1: Delete a reservation

PS C:\> Remove-DhcpServerv6Reservation -ComputerName "dhcpserver.contoso.com" -IPAddress 2001:4898:7020:1020::1,2001:4898:7020:1020::2

This example deletes the reservation for the specified IPv6 addresses.

Example 2: Delete all reservations for a scope

PS C:\> Remove-DhcpServerv6Reservation -ComputerName "dhcpserver.contoso.com" -Prefix 2001:4898:7020:1020::

This example deletes all of the reservations from the specified IPv6 scope.

Example 3: Delete all reservations for all scopes

PS C:\> Get-DhcpServerv6Scope -ComputerName "dhcpserver.contoso.com" | Remove-DhcpServerv6Reservation -ComputerName "dhcpserver.contoso.com"

This example deletes all of the reserved IP addresses from all of the DHCPv6 scopes on the DHCP server service that runs on the computer named dhcpserver.contoso.com. The Get-DhcpServerv6Scope cmdlet returns all of the scope objects and pipes the objects into this cmdlet, which deletes the reservations from each of the scopes passed 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: CimSession[]
Parameter Sets: (All)
Aliases: Session

Required: False
Position: Named
Default value: None
Accept pipeline input: False
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 IPv6 addresses of the reservations that 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.

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)
