<br>
Our network has a lot of /30 and /31 subnets, designed for a single <br>
device on a single switchport. So our kea configuration includes lots of <br>
subnets with only 1 address in the DHCP pool. We currently issue <br>
addresses using the DHCP relay address, and this works very well.<br>
<br>
But we have some mobile devices that move from port to port, and they <br>
occasionally cannot receive an address because the last device to attach <br>
to that switchport is still holding the lease.<br>
<br>
We would like to configure kea to prevent it from storing leases for <br>
these subnets: if another device attaches to that switchport, we'd like <br>
kea to re-issue the address. (Note that we also have some traditional <br>
networks, and we prefer kea to record and track leases normally for <br>
those subnets).<br>
<br>
Is this behavior currently supported? Or will it require new <br>
development or external integration to remove the lease from the <br>
database?<br>
<br>
Thank you,<br>
David Potter<br>
