Hi Isaac, I think that kea-dhcp-ddns just uses standard nsupdate commands as described by RFC no matter the brand of server on the other end. You might be interested in: https://gitlab.isc.org/isc-projects/kea/-/issues/3257 which would prevent frequent updates from clients to DNS servers based on the cached lease threshold settings in Kea (https://kea.readthedocs.io/en/kea-2.4.1/arm/dhcp4-srv.html#lease-caching).
