Hi

I  try to set up an DHCP request from an Client named  node2.cluster01.darkwing.net.
The IP is generated fine, however  syslog reads:

Nov 21 16:41:39 dnsdcp kea-dhcp4[840]: 2023-11-21 16:41:39.909 INFO  [kea-dhcp4.leases/840.140172516175488] DHCP4_LEASE_ADVERT [hwtype=1 08:00:27:b0:d3:33], cid=[no info], tid=0x1cef137                 9: lease 192.168.100.151 will be advertised

^C

As far as i got it I have to define the Forward ddns Domains in kea-dhcp-ddns.conf.
Which I’ve done:

"forward-ddns" : {
      "ddns-domains" : [
          {    "name": "darkwing.net.",
               "key-name": "dhcp1-ns1",
               "dns-servers":
                        [
                        { "ip-address": "192.168.100.41" }
                        ]
                },
        {        "name": "cluster01.darkwing.net.",
               "key-name": "dhcp1-ns1",
               "dns-servers":
                        [
                        { "ip-address": "192.168.100.41" }
                        ]
          }
      ]
  },

It is defined lin named.conf.local, too

zone "cluster01.darkwing.net" IN {
        type master;
        file "/var/lib/bind/db.cluster01.darkwing.net.zone";
        update-policy { grant dhcp1-ns1 wildcard *.darkwing.net A DHCID;};
};

I guess, it is an „admin too stupid errror“…
But which?
Thx
Christian
