<span><span>Hi Christian,</span></span>
<div><span> DNS updates are performed by the kea-dhcp-ddns (aka d2) process on receipt a "Name Change Request" (NCR).
</span></div>
<div><span>You would need to change the ip address in the NCR sent from Kea to enable sort of behaviour.</span></div>
<div><span>The behavioral parameters for ddns in kea-dhcp4 configuration are: </span>
