Hello,
Here is another use case which does not strictly abides to RFCs:
When a client sends a Request with a specific IP address which is already
leased to someone else, Kea sends back an "Ack" with another (available) IP
address.
According to RFC2131, a DHCPNAK should be returned in this case:
If the selected server is unable to satisfy the DHCPREQUEST message
(e.g., the requested network address has been allocated), the
server SHOULD respond with a DHCPNAK message.
This is somehow similar to the issue described in:
http://kea.isc.org/ticket/3592
Regards,
Nicolas.
