Hi,
On that topic, I see that [Kea-users] ip-reservations-unique and lease conflict
(isc.org)<https://lists.isc.org/pipermail/kea-users/2022-October/003548.html>
did not get an answer.
Has anyone else encountered the same issue as Marc ?
Thanks,
Veronique

Hi -m,
You can use the "ip-reservations-unique": false,
See:
