>> I encourage you to open an issue at
https://gitlab.isc.org/isc-projects/kea to request a feature to enable your
use case. I seem to remember we once discussed some sort of ‘automatically
create a reservation’ feature but I didn’t really understand the use case
for it. It really helps when users describe how they expect the feature to
work.  For example, how do you know what to put in the HR to identify the
client if you don’t have any identifier for the client??

I'm probably able to configure them to change their behaviour into
something that would work for me. I will look a bit more into it and get
back to you if I find that such a feature still seems legit. It's certain
that KEA does nothing wrong in this case, so this feature would ask it to
refrain from following standards by ignoring the DHCP release package.

Hi again, Vicky,

With the excellent tip I got from Peter Davies about using the built-in
DROP client-class, which adds the functionality I'm after, I see no reason
to open an issue about this. My problem is solved and I'm even more happy
with KEA :-)

Greetings,
Johannes
