First of all, the calls being used by applications are not system calls. Not the definition of system calls I know of at least.

The difference between traditional DNS and what we have here to be is that in traditional DNS the configuration and control of where to send the DNS packets is made by the operating system, while with ADD it is done by the application.

The rest of the stuff is very similar. Still RD flag set. Still not much clue on the client side etc.

Then, as others have said, discussion about other transport protocols have been sneaking in here, but that does not really matter for me when talking about traditional DNS or ADD. Do53 or DoT or whatever is just another transport.

Good to define the terms though! But if you have different DoT things for when RD flag is set or not, why not also for Do53?
