Hi -m,
You can use the "ip-reservations-unique": false,
See:

Greetings,
I'm migrating from ISC DHCPD to Kea.
I have a laptop on my network that I want to get the same IP address
if it is connected via wifi or if it is plugged in to hard-wired
ethernet. This was possible in ISC DHCPD.
In Kea I have database entries:
# select * from hosts_human where hostname ~ 'zirconium';
hostname │ mac_address │ ip_address
════════════════╪═══════════════════╪═══════════════
zirconium-wlo1 │ bc:17:b8:cb:8b:94 │ 192.168.0.226
zirconium-eno1 │ 0c:37:96:1f:04:ef │ 192.168.0.226
(2 rows)
..but I get errors from the server:
Oct 09 19:21:07 zed kea-dhcp4[5515]: INFO DHCP4_LEASE_ADVERT
[hwtype=1 bc:17:b8:cb:8b:94], cid=[01:bc:17:b8:cb:8b:94],
tid=0x2c7fc3e4: lease 192.168.0.226 will be advertised

tid=0x2c7fc3e4: error during attempt to allocate an IPv4 address:
multiple records were found in the database where only one was
expected for query get_host_subid_addr
Am I missing something to allow this particular configuration?
Or is it not possible in Kea (to do what was possible in ISC DHCPD)?
Thanks for any help!
