Description
The Remove-DhcpServerv4Reservation cmdlet deletes the IPv4 reservation from the specified scope. If the ScopeId parameter is specified, all of the reservations from the scope are deleted. If you specify the IPAddress or ClientId parameter, one or more specific reservations identified by IP addresses or client identifiers (IDs) are deleted.
Examples
Example 1: Delete all reservations in a scope
PS C:\> Remove-DhcpServerv4Reservation -ComputerName "dhcpserver.contoso.com" -ScopeId 10.10.10.0
This example deletes all of the reservations in the specified scope.
Example 2: Delete specified reservations
PS C:\> Remove-DhcpServerv4Reservation -ComputerName "dhcpserver.contoso.com" -IPAddress 10.10.10.5, 10.10.10.6
This example deletes the specified reservations from the DHCP server service.
Example 3: Delete reservations for a specified client
PS C:\> Remove-DhcpServerv4Reservation -ComputerName "dhcpserver.contoso.com" -ScopeId 10.10.10.0 -ClientId "F0-DE-F1-7A-00-5E"
This example deletes the specified reservation identified by client ID from the DHCP server service. For computers that run the Windows operating system, the MAC address is used as a client identifier.
Example 4: Delete reserved IP addresses from all scopes
PS C:\> Get-DhcpServerv4Scope -ComputerName "dhcpserver.contoso.com" | Remove-DhcpServerv4Reservation -ComputerName "dhcpserver.contoso.com"
This example deletes all of the reserved IP addresses from all of the scopes on the DHCP server service that runs on the computer named dhcpserver.contoso.com. The Get-DhcpServerv4Scope cmdlet returns all of the scope objects and pipes the objects into this cmdlet, which deletes the reservations from each scope passed in 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.

The throttle limit applies only to the current cmdlet, not to the session or to the computer.
