[<CommonParameters>] 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.
Examples
Example 1: Remove an IP address block
PS C:\> Get-IpamBlock -NetworkId "10.15.0.0/16" -StartIPAddress 10.15.0.0 -EndIPAddress 10.15.255.255 | Remove-IpamBlock
Confirm
Deleting IP address block with NetworkId 10.15.0.0/16 from IPAM. Deleting the block may move the currently mapped IP address ranges within this block to Unmapped address space.Do you want to continue?
[Y] Yes [N] No [S] Suspend [?] Help (default is "Y"): YThis command removes the IP address block from the network that has the ID 10.15.0.0/8/16. The command specifies the start and end addresses for the address block.
Example 2: Remove all child IP address ranges that belong to an address block
PS C:\> Get-IpamBlock -NetworkId "10.0.0.0/8" -StartIPAddress 10.0.0.0 -EndIPAddress 10.255.255.255 | Remove-IpamBlock -DeleteAssociatedSubBlocks
Confirm
This will permanently delete the given IP Block with NetworkId 10.0.0.0/8 from IPAM. Deleting the block may move the currently mapped IP address ranges within this block to Unmapped address space. Any sub-blocks associated with the given block will also be deleted. Do you want to continue?
[Y] Yes [N] No [S] Suspend [?] Help (default is "Y"): YThis command removes all child IP address ranges that belong to the address block from the network that has the ID 10.0.0.0/8. The command specifies the start and end addresses for the 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.

-InputObject
Specifies the input to this cmdlet. You can use this parameter, or you can pipe the input to this cmdlet.
| Type: | CimInstance[] |
| Position: | Named |
| Default value: | None |
| Required: | True |
| Accept pipeline input: | True |
| Accept wildcard characters: | False |
-NetworkId
Specifies the IP network prefix, in Classless Interdomain Routing (CIDR) notation, for the network blocks to be deleted.

-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.
