Same here.

As a non-expert, I find the confusion between network, address,
address with mask, etc to be extremely unhelpful. I haven't looked to
confirm if it's a confusion that only exists in the discussion, or if
it's in the code as well. However, from my POV, I'd rather have a
module that made the concepts clear and unambiguous, effectively
educating me in the details of correct usage while I used it, rather
than one that catered to my muddled thinking and allowed me to remain

Of course, the discussion seems to imply that even the experts have a
confused view, so maybe I'm being too ambitious here :-)
