migrate to a modern DHCP server solution
Good old isc-dhcpd won’t be maintained anymore in the future so it’s time to plan to migrate to a new DHCP solution.
ISC Kea https://www.isc.org/kea/ is the modern successor and brings a modular and extensible design.
It brings DHCPv4 and DHCPv6 (for those who want that …), DDNS.
It brings the “Control Agent” with powerful APIs to manage the Kea server.
A great enhancement is “Stork” , a graphical dashboard for monitoring multiple Kea servers (which can be run in High Availability clusters).
I currently work on a migration project from isc-dhcpd-cluster to a kea-cluster and look forward to support more customers doing that.
isc-dhcpd might be kept available in smaller appliances like routers and access points for a long time. It’s also expected that linux distributions will keep it backported for quite a while. But it won’t be developed anymore, so migrating to Kea might be the better solution.
Getting a modern WebGUI alone is a key feature worth doing so IMO.
