<div>I had a look at the migration document (<a href="https://kea.isc.org/wiki/ConfigurationMigration" target="_blank">https://kea.isc.org/wiki/<wbr>ConfigurationMigration</a>)</div>

<div>I found shared-network in the table and noted that no Kea

doesn't seem to show a way to group subnets together.</div>

<div>Is there presently no way to do something like this?:</div>

<tt>Hello:<br>
<br>
It depends on what you are using the shared-network feature to
accomplish. For ISC DHCP, a shared-network implies that the
subnets therein are the same physical interface. It is also true
that the subnets inherit any statements (such as options) from the
shared-network. Could you expand on your needs?<br>
<br>
Thanks,<br>
