after a reboot the system (Fedora 35) comes up like this:
# ss -tulpn | grep kea
udp UNCONN 0 0 0.0.0.0:44267 0.0.0.0:*
users:(("kea-dhcp6",pid=734,fd=16))
udp UNCONN 0 0 127.0.0.1:53001 0.0.0.0:*
users:(("kea-dhcp-ddns",pid=728,fd=10))
udp UNCONN 0 0 0.0.0.0:45047 0.0.0.0:*
users:(("kea-dhcp4",pid=731,fd=16))
udp UNCONN 0 0 10.0.0.10:67 0.0.0.0:*
users:(("kea-dhcp4",pid=731,fd=19))
after restarting kea-dhcp6 it looks like this:
# ss -tulpn | grep kea
udp UNCONN 0 0 127.0.0.1:53001 0.0.0.0:*
users:(("kea-dhcp-ddns",pid=728,fd=10))

- What are the extra ports - beyond 67 and 547 - good for?
- Why does kea-dhcp6 always need a restart?
- Why does kea-dhcp6 bind to [ff02::1:2] if it is configured to get requests
via a dhcp relay?
