Get-DhcpServerv6FreeIPAddress

Gets one or more free, or unassigned, IPv6 addresses from the specified scope.

Syntax

Parameter Set: Get0
Get-DhcpServerv6FreeIPAddress [-Prefix] <IPAddress> [[-NumAddress] <UInt32> ] [-AsJob] [-CimSession <CimSession[]> ] [-ComputerName <String> ] [-EndAddress <IPAddress> ] [-StartAddress <IPAddress> ] [-ThrottleLimit <Int32> ] [ <CommonParameters>]

Detailed Description

The Get-DhcpServerv6FreeIPAddress cmdlet gets one or more free IPv6 addresses from the specified scope.

If the NumAddress parameter is specified, then the requested number of free IPv6 addresses are returned. If the NumAddress parameter is not specified, then a single free IPv6 address will be returned. The maximum number of free IPv6 addresses returned is capped at 1024.

If the StartAddress parameter is specified and the EndAddress parameter is not specified, then the free IPv6 addresses starting from the specified StartAddress parameter value through the ending of the IPv6 address range of the scope are returned.

If the EndAddress parameter is specified and the StartAddress parameter is not specified, then the free IPv6 addresses starting from the beginning of the IPv6 address range of the scope through the specified EndAddress parameter value are returned.

If both of the StartAddress and EndAddress parameters are specified, then the free IPv6 addresses between the specified StartAddress and EndAddress parameter values are returned.

The exclusion address ranges, reservations, active, offered and bad, or declined, leases are excluded while returning free IPv6 addresses.

The IPv6 address ranges associated with a policy will be included while returning free IPv6 addresses.

The IPv6 addresses which are in expired, or doomed, state will be included while returning free IPv6 addresses.

If the requested number of free IPv6 addresses could not be found, then a warning is displayed.

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.

-ComputerName<String>

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

-EndAddress<IPAddress>

Specifies the ending IPv6 address of the range from which the free IPv6 addresses are to be returned.

-NumAddress<UInt32>

Specifies the number of free IPv6 addresses requested.

-Prefix<IPAddress>

Specifies the IPv6 subnet prefix of the scope from which one or more free IPv6 addresses are requested.

-StartAddress<IPAddress>

Specifies the starting IPv6 address of the range from which the free IPv6 addresses are to be returned.

-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.
