This is an engineering drop of the Kea project constructed prior to the Kea 0.9 release. It introduces a new feature in Kea, DHCP-driven DDNS events. Kea's DHCP servers can now be configured to cooperate with a new server, DHCP-DDNS, to publish updates to DNS data based on changes in DHCP leases. DHCP-DDNS's operation and configuration is discussed in Chapter 19 of the Bind10 Guide. Additions to Chapters 17 and 18 describe configuring the DHCP servers to work with the DHCP-DDNS.
