Remove-DhcpServerv4Reservation is accessible with the help of DHCPServer module. To configure DHCPServer, go through this link.
Synopsis
Deletes the IPv4 Reservation from the specified scope.
Description
The Remove-DhcpServerv4Reservation cmdlet deletes the IPv4 reservation from the specified scope. If the ScopeId parameter is specified, then all of the reservations from the scope are deleted. If the IPAddress or ClientId parameter is specified, then one or more specific reservations identified by IP addresses or client identifiers (IDs) are deleted.
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.
