Abstract
In a data center that includes a number of chassis, with each chassis including a chassis management module and a number of slots, each slot associated with a service processor: network address assignment includes discovering, by a chassis management module of a particular chassis, one or more other chassis management modules; negotiating, by the chassis management module with the other chassis management modules via IPv6 data communications, a chassis-specific range of IPv4 addresses available for assignment to service processors of the particular chassis; providing, by the chassis management module to the service processors of the particular chassis, in dependence upon the chassis-specific range of IPv4 addresses, a base IPv4 address; and determining, by each service processor of the particular chassis, in dependence upon the base IPv4 address and a slot identifier of the slot associated with the service processor, an IPv4 address for the service processor.
