[Kea-users] Adding a lease via lease4-add API call

[Marek Greško]

Hello,

- can I add a lease with an IP of a given subnet but outside of a particular pool?

Yes for sure. If the lease exists it takes precedence even before an existing reservation which makes a headache for me.

- does kea actually use the lease to assign the IP? I mean, can this feature be used as a poor man's alternative to the JSON/DB based concept of host reservation?

Yes it does and no, it cannot be used. The lease is time limited and then disappears if the device is off for some time. Your pseudo reservation will then be gone.
