Thank you for your comment. I understand it.

So, I think that if the registry makes the wild-card or some synthesis
response name server, it works well in this situation.

But I know that some old caching nameserver is not effective.
Many old nameservers are still working in the internet. :-(

I will make demonstration environment and test it.
