Hi all.

Our network has a lot of /30 and /31 subnets, designed for a single device on a single switchport. So our kea configuration includes lots of subnets with only 1 address in the DHCP pool. We currently issue addresses using the DHCP relay address, and this works very well.

But we have some mobile devices that move from port to port, and they occasionally cannot receive an address because the last device to attach to that switchport is still holding the lease.

We would like to configure kea to prevent it from storing leases for these subnets: if another device attaches to that switchport, we'd like kea to re-issue the address. (Note that we also have some traditional networks, and we prefer kea to record and track leases normally for those subnets).

Is this behavior currently supported? Or will it require new development or external integration to remove the lease from the database?

Thank you,
David Potter
