Hi Christoph, Please can you share your configuration? Whether Kea replaces hostnames, generates dynamic hostnames and / or honors the clients wishes from the flags in option 39 (all described here: https://kea.readthedocs.io/en/stable/arm/dhcp6-srv.html#ddns-for-dhcpv6) depend on several settings in the configuration. Option 39 flags and their meanings are described in the ARM (https://kea.readthedocs.io/en/stable/arm/dhcp6-srv.html#when-does-the-kea-dhcp6-server-generate-a-ddns-request) and in RFC4704 (https://datatracker.ietf.org/doc/html/rfc4704). There does seem to be some strange behavior here, but without additional information it is impossible to say what is happening and whether is *should* be.
As for the log messages, this one "no static reservations available" is "ALLOC_ENGINE_V6_ALLOC_UNRESERVED" which is described here: https://kea.readthedocs.io/en/stable/kea-messages.html#alloc-engine-v6-alloc-unreserved and this one "no leases found but reservations" is "ALLOC_ENGINE_V6_ALLOC_NO_LEASES_HR" and is described here: https://kea.readthedocs.io/en/stable/kea-messages.html#alloc-engine-v6-alloc-no-leases-hr As for the reason for these messages, I could only guess without seeing the full configuration.
