This does not seem to be intended behavior:

Hello Marek,
kea listens on UDP socket only for port 546. You should not use -t flag with
netstat which shows only TCP.

I have not been able to find a workaround for this problem on IPv6 side for
now.

I need to figure this out also, as I run Kea in a container that can be
destroyed and rebuilt anytime. I am thinking I will update the Kea config via
a shell script run on boot/init.
Would be nice if there was a "listen on all" option like 0.0.0.0 does for IPv4,
but all the docs I have read
So I think I found the potential solution, though I am not sure I understand
why this happens. I had to specifically configure the unicast IPv6 address in
the “interfaces” clause, as follows
"interfaces-config": {
"interfaces": [
"enp6s18/2600:6ce4:0:42::130"
]
},
I guess netstat is deprecated. “ss” seems to show the binding but … only
to a link local address for some reason on the v6 side.
root@server-kea-node1:~# ss -tulpn
Netid State Recv-Q Send-Q
Local Address:Port Peer Address:Port Process
I wonder whether it has anything to do with the fact that DHCPv6 process
does not seem to listen on port 546
root@server-kea-node1:/home/kea # sudo netstat -tulpn | grep LISTEN
tcp0 0 127.0.0.1:8000 0.0.0.0:* LISTEN
628/kea-ctrl-agent
tcp0 0
Dear colleagues,
I have been attempting to test a setup in the lab with DOCSIS CM operating
in IPv6 mode only, where the DHCPv6 messages are relayed across the CMTS and
the first-hop router (relay address 2600:6ce4:0:3e::1) towards a Kea server
running 2.4 code (address 2600:6ce4:0:42::130).
