[Kea-users] Kea-DHCPv6: No static reservations available

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.

Thank you,
Darren Ankney

Kea assigns the correct IPv6 address ,but it doesn't recognize the hostname. I don't understand why Kea states the following messages in the log: 'no leases found but reservations' / 'no static reservations available'.
