[Kea-users] DHCP4 reservation by DNS hostname lookup - how?

[Jeff Armstrong]

In the isc-dhcp-server I could use DNS to make reservations:

host gh-ja-iphone-uk { hardware ethernet 
5b:c7:43:37:a2:b0;fixed-addressja-iphone-uk.gh.mydomain.com; }
and the IP assigned would be retrieved from DNS.

In Kea I have tried:

"reservations": [
       { "hw-address": "5b:c7:43:37:a2:b0", "fixed-address": 
"ja-iphone-uk.gh.mydomain.com"}
     ]
"reservations": [
       { "hw-address": "5b:c7:43:37:a2:b0", "ip-address": 
"ja-iphone-uk.gh.mydomain.com"}
     ]
"reservations": [
       { "hw-address": "5b:c7:43:37:a2:b0", "host-name": 
"ja-iphone-uk.gh.mydomain.com"}
     ]
but these don't work - the first two stop the server from starting with 
a configuration error, and the third just assigns from the pool.
I have read 
https://kea.readthedocs.io/en/kea-2.6.1/arm/dhcp4-srv.html#host-reservations-in-dhcpv4 
- but cannot find a clear list of all the recognised options for 
reservations.
Help?!?
Many thanks,
Jeff
