Hello,
I was using ISC DHCP server and used the group concept to define common
parameters for a group of clients. I found this concept very convenient. Is it
possible to define something like group in the kea dhcp server reservations or
should I define specific parameters to every host in reser
Hmm, I would expect reservations are not offered if not within the subnet.

If you update slave DNS server by DDNS you would probably get rejected as it is
not authoritative for the zone. So I would say it is neither DNS nor Kea issue
but parameters returned by kea should be changed to honor DDNS updates towards
the primary DNS server.

Hello Albert,
I am not a real expert on kea, but I can add my 2 cents. We have been using
dhcpd, which config was generated by shell script. So we only modified it to
generate kea config. The main advantage of kea compared to dhcpd is that kea
enables you to include another config file using

Yes for sure. If the lease exists it takes precedence even before an existing

Hello Cristina,
dhcpv6 does not match on MAC address. You should match on DUID. You can find
the correct DUID for the client in the leases file.
So the reservation should look like this:
{"hostname": “X”,”duid": “00:01:00:.:XX:YY:ZZ:AA:00:0o”,”ip-addresses":
["2001:760:422c:35::XYZ”] }
Hello Marek,
kea listens on UDP socket only for port 546. You should not use -t flag with
netstat which shows only TCP.

Hello,
I have working kea dhcpv6 setup. I am struggling with one problem. All my
devices get correct IPv6 addresses from reservations by matching DUID. But one
of the devices in the network have changing DUID, only the DUID-LL part is
constant, so I tried to match on DUID-LL. I am convinced it
If nothing else you should also just be able to specify DUID-LL directly:

Nope, solution is to not place reservations into leases. The reservations in
leases create more problems then it solves. There are many change requests for
it from multiple people. This was just step sidewards.

Hello,
I suspect, you just hit major design flaw of the kea. It is storing the
reservation into the lease file and the lease has precedence when responding to
the client. So if your client asked for a ip address and received some from the
pool and you added the reservation after that, you will
Hello,
