Reservation

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.
