[<CommonParameters>] Description
The Add-DhcpServerv4Reservation cmdlet reserves the specified IPv4 address in the scope for a client. Once reserved, the IP address will be leased only to the client identified by the specific client identifier (ID).
Examples
EXAMPLE 1
PS C:\> Add-DhcpServerv4Reservation -ScopeId 10.10.10.0 -IPAddress 10.10.10.8 -ClientId F0-DE-F1-7A-00-5E -Description "Reservation for Printer"This example adds a reserved IP address for the client identified by the specified client ID.
EXAMPLE 2
PS C:\>Import-Csv -Path Reservations.csv | Add-DhcpServerv4Reservation -ComputerName dhcpserver.contoso.comThis example adds all of the reservations in the file named Reservations.csv to the DHCP server service running on the computer named dhcpserver.contoso.com. The Import-Csvhttp://go.microsoft.com/fwlink/p/?LinkId=113341 cmdlet returns the objects with reservation fields and pipes the objects to this cmdlet, which adds these reservations to the DHCP server services. The file named Reservations.csv should contain the reservations in the following comma-separated values (CSV) format:
ScopeId,IPAddress,Name,ClientId,Description
10.10.10.0,10.10.10.10,Computer1,1a-1b-1c-1d-1e-1f,Reserved for Computer1
20.20.20.0,20.20.20.11,Computer2,2a-2b-2c-2d-2e-2f,Reserved for Computer2
30.30.30.0,30.30.30.12,Computer3,3a-3b-3c-3d-3e-3f,Reserved for Computer3
EXAMPLE 3
PS C:\>Get-DhcpServerv4Lease -ComputerName dhcpserver.contoso.com -IPAddress 10.10.10.11 | Add-DhcpServerv4Reservation -ComputerName dhcpserver.contoso.comThis example converts one of the leases into a reservation. The Get-DhcpServerv4Lease cmdlet returns the IP address lease object and pipes the object to this cmdlet, which creates the reservation with the IP address and client ID in the lease object.
EXAMPLE 4
PS C:\> $freeip = Get-DhcpServerv4FreeIPAddress -ComputerName dhcpserver.contoso.com -ScopeId 10.10.10.0
PS C:\> Add-DhcpServerv4Reservation -ComputerName dhcpserver.contoso.com -ScopeId 10.10.10.0 -IPAddress $freeip -ClientId F0-DE-F1-7A-00-5E -Description "Reservation for Printer"This example creates a reservation for the client identified by the specified client ID from any of the free IP addresses in the scope 10.10.10.0. The Get-DhcpServerv4FreeIPAddress cmdlet fetches a free IP address in the scope, then this cmdlet reserves an address for the specified client ID.
