After trying to find out more about this "offline" status, it still seems to be rather vaguely defined.

Usually it is offered as paid feature (by noip and dyn) that somehow redirects to a different IP / URL when offline status is active, so that either some "this site is offline" message can be shown or some other content specified by the user.

To support "offline" on dns level, we would just give another IP as answer if the client is offline.

The IP would be either:
a) a (fallback-)IP provided by the user
b) an IP from the nsupdate.info service provider (with a http server just telling "it's offline" as response to ANY request)

I find a) of limited usefulness, but at least it might have some use case. Of course, the client could just send a normal update with myip=FALLBACKIP and the result would be the same.

b) is even more useless and requires additional resources (separate IP + respond-to-all web server) at the service provider, just to tell "it is not online", what everybody would have guessed anyway if there's no response because the IP is offline.

So, I guess I'll put this feature on HOLD status until someone can provide a real usecase.

If somebody has a paid dyn or noip subscribtion and can tell us usecases for the offline mode and what options there shall be, please do tell.

Just another note why the offline flag doesn't help for deletion of A or AAAA record:

We need the capability to selective delete the A or AAAA (or both) records.

Just sending offline=YES would not allow to specifically delete only one of these records as without further information, the server would not know which one.

seem like useless and there's also no big interest in this. thus, closing this for now.

in case somebody reopens: please give a usecase and describe the scenario precisely.
