Hello Pawel: Just wanted to update you on your feature request to be able to turn on/off conflict resolution in kea-dhcp-ddns (aka D2). We will keep it in mind for future releases, but has been deemed not-in-scope for our next release Kea 1.3 which should be out sometime in 2017 (firm date is TBD).
