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.

Examples

EXAMPLE 1

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

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

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 Windows computers, the MAC address is used as a client identifier.

EXAMPLE 4

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 running 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 of the scopes passed in through the pipeline.

Required Parameters
