   I'm kind of the same way. It's SO complex under
   the hood ... well ... it'd better Just Work.

   I know I'm asking for something a bit out of the
   ordinary. There have been a few proposed options
   I'm gonna look into. However I'm not gonna
   massively edit huge scripts or config files,
   requiring arcane knowledge. The more "standard"
   the better.

   The modern environment CAN use up more than 254
   addresses - or at least CROWD the 254 so badly
   that it's hard to organize. With "IOT" stuff
   this will just get WORSE.
