Hi, thanks for that email, let me paste parts of it in.
I didn't find any clear definition of how DDNS works in that email.

So, explain to me that this part works: "the NAS performs DynDNS registration"?
First, are you talking about RFC3007? No, I don't think so. What's the
Performance Specification that describes this process? Yes, I know where
the vendor specific documentation is.
Second, how are the credentials for that communication established?
What name does your NAS pick? How did you communicate the credential to the
NAS?
Once the 14 year old in the house does this, how does the parent find out
about the name that was used?
Was it IPv4, IPv6 (and from which ISP, as our homenet architecture says we
can have more than one ISP. That's why we did all that BABEL stuff, right?),
and did the device publish a SLAAC derived IP, a privacy IP, a stable IPv6?
If the device renumbers, or experiences a flash renumbering, how does it know
to re-register?
So, let me know the details here, as these are the kind of things the HNA
mediated zone is dealing with.

All sorts of devices can be buggy.
I don't expect to be dependent upon a buggy NAS either.
