Reservation

The Reservation Object defines a mapping between a token and an IP address. The token is defined by the assigned strategy. Similar to the subnet object, the only current strategy is MAC. This will use the MAC address of the incoming requests as the identity token. The reservation allows for the optional specification of specific options and a next server that override or augment the options defined in a subnet. Because the reservation is an explicit binding of the token to an IP address, the address can be handed out without the definition of a subnet. This requires that the reservation have the netmask option (DHCP option 1) specified. In general, it is a good idea to define a subnet that will cover the reservation with default options and parameters, but it is not required.

Reservations are what the DRP DHCP service uses to ensure that an IP address is always issued to the same device.

Field	Definition
Strategy	The strategy that the DHCP service should use to determine whether this reservations should be used.
Token	The string that the strategy uniquely identifies a network interface with.
Address	The IP address that is being reserved.
Options	The DHCP options that should be returned when creating or renewing a Lease based on this reservation.

Note

If you create a static reservation, DRP will always respond to the request even if the subnet is disabled.

Note

If the reservation and its subnet, if present, define both option 12 and option 15, this will be used to find a matching DNS Zone for automatic A and PTR record creation.
