Abstract

A method and apparatus for providing network addresses for hosts on a network includes generating and storing network configuration information in a subnet management process, where a subnet is a set of contiguous network addresses. The network configuration information indicates network addresses to be distributed among a plurality of network devices. Policy information is also generated and stored. The policy information indicates a policy set of one or more policy processes. Each policy process selects an available subnet from available network addresses. A request for a subnet is received from a subnet requesting process. A particular subnet is determined based on the network configuration information, the request, and the policy set. A response indicating the particular subnet is sent to the subnet requesting process. These techniques allow an administrator to choose a policy for selecting subnets that better utilizes network resources for a wide range of network architectures.
