I've configured both DHCPv6 and DDNS. DHCPv6 leases are working properly, but
DDNS is not triggered.
I'm wondering if this is configuration related or some other issue?
DHCP4 in combination with DDNS is working fine.
The version of kea is 1.0.0
I'm using the following configuration.
DHCP6:
"dhcp-ddns": {
"enable-updates": true,
"override-client-update": true,
"override-no-update": true,
"generated-prefix": "host",
"qualifying-suffix": "home.vforge.net."
},
DDNS:
"forward-ddns": {
"ddns-domains": [
{
"name": "home.vforge.net.",
"key-name": "dhcp-update",
"dns-servers": [
{ "ip-address": "192.168.10.53" },
{ "ip-address": "2001:610:64f:10::100:53" }
]
}
]
},
"reverse-ddns": {
"ddns-domains": [
{
"name": "10.168.192.in-addr.arpa.",
"key-name": "dhcp-update",
"dns-servers": [ { "ip-address": "192.168.10.53" } ]
},
{
"name": "0.1.0.0.f.4.6.0.0.1.6.0.1.0.0.2.ip6.arpa.",
"key-name": "dhcp-update",
"dns-servers": [ { "ip-address": "2001:610:64f:10::100:53" } ]
}
]
}
The debug log of DHCP6 shows the following entries when a client requests an IP
address:
