Syntax

Parameter Set: ByKeySet
Remove-IpamBlock [-NetworkId] <String[]> [-StartIPAddress] <IPAddress[]> [-EndIPAddress] <IPAddress[]> [-AsJob] [-CimSession <CimSession[]> ] [-DeleteAssociatedSubBlocks] [-Force] [-PassThru] [-ThrottleLimit <Int32> ] [-Confirm] [-WhatIf] [ <CommonParameters>]

Parameter Set: InputObject (cdxml)
Remove-IpamBlock -InputObject <CimInstance[]> [-AsJob] [-CimSession <CimSession[]> ] [-DeleteAssociatedSubBlocks] [-Force] [-PassThru] [-ThrottleLimit <Int32> ] [-Confirm] [-WhatIf] [ <CommonParameters>]




Detailed Description

The Remove-IpamBlock cmdlet removes an IP address block from IP Address Management (IPAM). Specify an address block by using the StartIPAddress and EndIPAddress parameters, or use the InputObject parameter to specify the input to this cmdlet. You can specify the DeleteAssociatedSubBlocks parameter to remove all the child IP address ranges mapped to the address block. When you remove an address block, IPAM remaps all subnets and unmaps some subnets which it previously mapped to an address block.

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.
