Hi, how does one make use of the ddns fix, ie are there any configs changes required?

Hi,

The patch responds to "option-data", "code" : 15 in "subnet4" config allowing to specify multiple domains.
Example (not full config, only relevant fields):

{ "Dhcp4": { "subnet4": [ { "id": 11, "option-data": [ { "code": 15, "data": "r1h.nue", "name": "domain-name" } ] }, { "id": 21, "option-data": [ { "code": 15, "data": "r1m.nue", "name": "domain-name" } ] }, { "id": 31, "option-data": [ { "code": 15, "data": "r1v.nue", "name": "domain-name" } ] } ] } }

thanks for the quick reply, and the patch!

Hey @shaders and @binagun. Kea migrated to gitlab. Can I ask you to open an issue there, so this fix is on Kea engineers' radars? We don't look at github too often...
