Abstract
In general, techniques are described for a hierarchical, distributed DHCP system for managing IP address assignment among distributed networks of computing devices. For example, a system may include a central DHCP server configured to manage a plurality of distributed DHCP servers, each distributed DHCP server configured to perform DHCP using IP addresses allocated from a common prefix for a tenant associated with computing devices managed by multiple DHCP servers. The central DHCP server allocates IP addresses to the distributed DHCP servers, e.g., on an on-demand basis from the common pool and may handle concurrent requests for IP addresses from distributed DHCP servers. Each of the distributed DHCP servers may store records for IP addresses and media access control (MAC) addresses for computing devices managed by that distributed DHCP server, and the DHCP servers may send these records to the central DHCP server to facilitate IP assignment coherency.
