As far as I remember, it will look up the lease before reservations :)
If you modify the IP in the lease file, that is the ip it will get.

If you want to change the IP, delete the entry in lease table and make a new discover on the client. Then you should get the reservation ip inserted in lease table.

Subject: [Kea-users] Lease or reservation


Yesterday I installed Kea 1.1.0 to my Debian 8.6.0 system and it's working fine with Postgresql backend. In my network no dynamical IP poll avaiable, I only use reserved IP address for all hosts.

And I have a question.

When Kea send the reserved IP to the client, it's write this data of DHCP respone to the leases SQL table. My question is, If I modify the reserved IP for this host in host reservation SQL table and the lease is not expire when the client send a new DHCP request, which IP will including to the respone? The leased IP or the new reserved IP?

Thanks your help.

Best regards,

János Csőke
