Problem using Kea DHCP
«

Hello.
I'm having an issue with one reservation that's not working correctly. It's with a Raspberry Pi that I'm using as a DNS server for my network. The reservations for everything else works as it should.
I've copied everything over to Kea from ISC, and at first it seemed like everything was fine. After about an hour the reservation stops working, and Kea assigns an incorrect address to it after the initial lease runs out.
According to the logs it appears that there are several characters added to the front of the MAC address for the Pi's NIC in the cid causing it to assign it a different IP than the one that's reserved, and I can't figure out what's causing it. I don't have the issue at all while using ISC, and it has worked as intended for several years now.
I'm hoping that someone with more knowledge about this can point me to the direction of where the problem could be.
Thank you in advance for any help!
Sincerely,
Dan
Edit: In the first line in the attached log KEA does assign the correct address.

Do you have static reservations for dhcp, if you do make sure you exclude them from the subnet range. Learned that one the hard way myself.
So if you are using 192.168.2.120, make sure 192.168.2.120 is excluded from the dhcp pool.
Example in my network I have 192.168.2.2 thru 10 setup as reserved IP's, so my subnet dhcp pool is 192.168.2.11-192.168.2.199.

Thank you for the response.
Yes I do. The IPs available to DHCP is .2 to .25. All of the reservations are .26 - .254.
