[Kea-users] DHCPv4 Conflict resolution on MAC change

[Veronique Lefebure]

Hi Simon,

The problem is new in the sense that we did not have that "problem" when using ISC DHCP since it would not check for the existing leases in case of static IP host-reservation.

Cheers,
Veronique

Your problem isn’t new - it’s somewhat fundamental to complying with the RFCs. You will need to remove any existing lease for the IP before the IP can be allocated to another client.
I assume it doesn’t scale in terms of having multiple hell desk operators having to do manual steps - in which case, the answer is to build a tool into your management toolset allowing them to “click here to remove the lease” when they are altering the reservation details.
