I want to only use kea-dhcp6, which means I need VMs working as DHCP servers to provide IPv6 addresses to other devices so those clients can have IPv6 addresses. But I don’t care or need that my kea-dhcp6 servers themselves have IPv6 addresses or not.<o:p></o:p></span></div><div style="margin: 0in; font-size: 12pt; font-family: Aptos, sans-serif;"><span style="font-size: 11pt;"><o:p> </o:p></span></div><div style="margin: 0in; font-size: 12pt; font-family: Aptos, sans-serif;"><span style="font-size: 11pt;">But the problem is that in the documentation, I can see they give some examples which all put the redundancy configurations under the<span class="Apple-converted-space"> </span><b>Dhcp4</b><span class="Apple-converted-space"> </span>configuration section. Does it imply that in order to use the HA feature for kea-dhcp6 servers, my DHCP servers themselves must be configured to have their own IPv6 addresses? I don’t think this makes any sense since in reality we only need the connectivity between primary and secondary servers no matter this connectivity is based on IPv4 or IPv6.<o:p></o:p></span></div><div style="margin: 0in;
