Describe the Kea process for selecting a subnet/address and assigning options
It would be very helpful to have a clear and explicit write up, and/or a diagram showing what information is evaluated, in what order, in the process of determining what address will be offered to a client, and how the options are assigned.
While there will be exceptions that complicate this, what we are looking for first is, what is the default process for a new offer for a DHCPv4 client?
