Dynamic network address management

A system for network address management, the system comprising:

• at least one processor;
• and
• at least one non-transitory computer-readable medium storing instructions that, when executed by the at least one processor, cause the at least one processor to perform operations comprising:
• determining a creation of a namespace associated with a cluster of virtual computing instances (VCIs), each of the VCIs comprising a pod, each pod comprising one or more containers, the namespace having associated therewith a subset of computing resources of the cluster of VCIs;
• determining, by a network container plugin (NCP), a size of a first network address pool to allocate to the namespace based on a first specified subset prefix length specified in configuration information for the namespace, the network address pool comprising a plurality of network addresses in a subnet;
• reserving, by the NCP, the plurality of network addresses in the subnet exclusively for the namespace by allocating the first network address pool to the namespace;
• receiving an indication that a pod is added to the namespace;
• and
• in response to the receiving of the indication, assigning a network address from the first network address pool to the pod.
