Makes it seem like it was handed out dynamically. Static assignments with
fixed-address are not written to a lease file. They are also not sent to the
peer.
I'm not sure what is going on here.

Anyone using LeaseQuery to get lease details (such as option 82
agent.circuit-id)? Having some problems as noted below.

There is no lease for a static reservation but you can provision static
reservations to the lease file by omapi.
You will find things like this in the lease file in those cases
host foo {
dynamic;
host-identifier option agent.circuit-id "foo";
fixed-address 192.0.2.100;
}
host bar {
dynamic;
hardware ethernet 00:50:00:00:00:01;
fixed-address 192.0.2.101;
}
I have a patch that also allowes provisioning of hosts with host-identifier via
omapi.
Propably not the case here but I would still want to check.
Greetings
Christian

But if I restart the daemon, those changes are lost, aren't they? We have lots
of reservations...

no. That is the purpose for them to be in the lease file so that they are not
lost on restarts.
