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

Hi there,

I do observe a strange behaviour since a while now on KEA DHCPv6 (dual
stack with KEA DHCP v4 as well, but the problem does not occur on v4!). Kea
version is 2.6.3
Within my v6 configuration file, I do have the following entry:
....
// VMDatabaseServer
{
    //"hw-address": "52:54:00:ef:57:d9",
    "duid": "00:03:00:01:52:54:00:ef:57:d9",
    "ip-addresses": [ "fd00:192:168:3::3" ],
    "hostname": "v6-vmdatabaseserver"
    //"option-data":

    },

....

When restarting VMDatabaseServer, it doesn't get the hostname
'v6-vmdatabaseserver' assigned, but
'v6-fd00-192-168-3--3.local.markert.live.' 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'.

Here is the kea-dhcp6.log file excerpt:
