Add-DhcpServerv6Reservation

Adds an IPv6 Reservation to an IPv6 prefix or scope.

Syntax

Add-DhcpServerv6Reservation
   [-Prefix] <IPAddress>
   [-IPAddress] <IPAddress>
   [-ClientDuid] <String>
   [-Iaid] <UInt32>
   [[-Name] <String>]
   [-AsJob]
   [-CimSession <CimSession[]>]
   [-ComputerName <String>]
   [-Description <String>]
   [-PassThru]
   [-ThrottleLimit <Int32>]
   [-Confirm]
   [-WhatIf]

Description

The Add-DhcpServerv6Reservation cmdlet reserves a specified IPv6 address for the client identified by the specified Dynamic Host Configuration Protocol (DHCP) v6 unique identifier (ID) (DUID) and identity association ID (IAID).

Examples

EXAMPLE 1

PS C:\> Add-DhcpServerv6Reservation -Prefix 2001:4898:7020:1020:: -IPAddress 2001:4898:7020:1020::1 -ClientDuid 00-01-00-01-15-F9-7F-AB-F0-DE-F1-7A-00-5E -Iaid 234890455

This example reserves the specified IPv6 address for the specified ClientDuid and Iaid parameter values. After the reservation is added, the DHCP server service will assign only the specified IP address to the client request which contains the specified ClientDuid and Iaid parameter values.

EXAMPLE 2

PS C:\> Import-Csv -Path Reservations.csv | Add-DhcpServerv6Reservation -ComputerName dhcpserver.contoso.com

This example adds all of the reservations in the file named Reservations.csv to the DHCP server service running on the computer named dhcpserver.contoso.com. The Import-Csvhttp://go.microsoft.com/fwlink/p/?LinkId=113341 cmdlet returns the objects with reservation fields and pipes the objects to this cmdlet, which adds these reservations to the DHCP server service. The file named Reservations.csv should contain the reservations in the following comma-separated values (CSV) format:

Prefix,IPAddress,Name,ClientDuid,Iaid,Description

2001:4898:7020:1020::,2001:4898:7020:1020::1,Computer1,00-01-00-01-15-F9-7F-AB-F0-DE-F1-7A-00-5E,234890455,Reserved for Computer1

2001:4898:7020:1020::,2001:4898:7020:1020::2,Computer2,00-01-00-01-15-F9-7F-AB-F0-DE-F1-7A-00-6E,234890465,Reserved for Computer2

2001:4898:7020:1020::,2001:4898:7020:1020::3,Computer3,00-01-00-01-15-F9-7F-AB-F0-DE-F1-7A-00-7E,234890475,Reserved for Computer3

Example 3

PS C:\>$freeip = Get-DhcpServerv6FreeIPAddress -ComputerName dhcpserver.contoso.com -Prefix 2001:4898:7020:1020::



PS C:\>Add-DhcpServerv6Reservation -ComputerName dhcpserver.contoso.com -Prefix 2001:4898:7020:1020:: -IPAddress $freeip -ClientDuid 00-01-00-01-15-F9-7F-AB-F0-DE-F1-7A-00-5E -Iaid 234890455 -Description "Reservation for Printer"

This example creates a reservation for the client identified by the specified client ID from any of the free IP address in the scope 2001:4898:7020:1020::. The Get-DhcpServerv6FreeIPAddress cmdlet fetches a free IP address in that scope, then this cmdlet reserves the IP address for the specified client ID.

EXAMPLE 4

PS C:\> Get-DhcpServerv6Lease -ComputerName dhcpserver.contoso.com -IPAddress 2001:4898:7020:1020::11 | Add-DhcpServerv6Reservation -ComputerName dhcpserver.contoso.com -Prefix 2001:4898:7020:1020::

This example converts one of the leases into a reservation. The Get-DhcpServerv6Lease cmdlet returns an IP address lease object and pipes the object to this cmdlet, which creates the reservation with the IP address, client DUID, and IAID in the lease object.

-CimSession

Runs the cmdlet in a remote session or on a remote computer.
