2.1 Configuration parameters repository

2.1 Configuration parameters repository

The first service provided by DHCP is to provide persistent storage of network parameters for network clients. The model of DHCP persistent storage is that the DHCP service stores a key-value entry for each client, where the key is some unique identifier (for example, an IP subnet number and a unique identifier within the subnet) and the value contains the configuration parameters for the client.

For example, the key might be the pair (IP-subnet-number, hardware- address) (note that the "hardware-address" should be typed by the type of hardware to accommodate possible duplication of hardware addresses resulting from bit-ordering problems in a mixed-media, bridged network) allowing for serial or concurrent reuse of a hardware address on different subnets, and for hardware addresses that may not be globally unique. Alternately, the key might be the pair (IP-subnet-number, hostname), allowing the server to assign parameters intelligently to a DHCP client that has been moved to a different subnet or has changed hardware addresses (perhaps because the network interface failed and was replaced). The protocol defines that the key will be (IP-subnet-number, hardware-address) unless the client explicitly supplies an identifier using the 'client identifier' option. A client can query the DHCP service to retrieve its configuration parameters. The client interface to the configuration parameters repository consists of protocol messages to request configuration parameters and responses from the server carrying the configuration parameters.
