Thanks for asking. DDR requires having a SSL/TLS cert for the public IP address which is owned by the organization. So, this is not something an average person or organization is going to implement. Only large organizations or ISPs may want to do this setup and setting it up is not that tough either for them.

Thanks for the explanation. I was just seeing this yet another feature as an opportunity but did not have deep enough knowledge.
