Abstract
A system and method for allocating IP addresses for network devices using the dynamic host configuration protocol (DHCP) wherein the DHCP server returns the requested IP address every time the IP address is requested. A client identifier is generated for each network device as a function of the IP address. The client identifier is used in the DHCP options field of the DHCP parameter list in a DHCPDISCOVERY message. The DHCP server indexes the network device configuration parameters according to the client identifier and returns the same IP address each time the DHCP is queried.
