Hi guys.
Is it possible to make KEA do DDNS this way
....
"dhcp-ddns": {
"enable-updates": true
},
....
"subnet4": [
{
"id": 1,
"subnet": "10.3.0.0/22",
"ddns-override-client-update": false,
"valid-lifetime": 3600,
"max-valid-lifetime": 3600,
"pools": [
{
"pool": "10.3.1.10 - 10.3.1.20"
}
],
"option-data": [
{
"space": "dhcp4",
"name": "domain-name",
"code": 15,
"data": "hub.mine.priv"
},
....
"reservations": [
{
"hostname": "cromo",
"hw-address": "52:54:00:74:5b:08",
"option-data": [
{
"space": "dhcp4",
"name": "domain-name",
"code": 15,
"data": "private.way"
},
]
//"client-classes": [ "PRIVATE.ROAD" ]
},
....
/ddns-qualifying-suffix/ is absent, I read somewhere that in
it's absence /domain-name/ is used for DDNS then.
I'm hoping that subnet will do DDNS with one domain and if a
client has reservation with another domain, then such
"reserved" domain will be used, but..
KEA with such config is not doing DDNS at all I think - does
that make sense & is what I'm hoping for possible?
many thanks, L.
