Please implement Private DNS Zones. It's quite common in cloud hosts to provide this functionality. It's available in AWS, Azure, GCP, Oracle Cloud, etc.

We want it so we can use DNS lookups and not care if it's an internal or external hostname. It just works across the infrastructure... No more hard-coded IPs in /etc/hosts and other configuration files. It's a single place to update should an IP change instead of potentially hundreds or thousands of places.

Additional functionality: automatically populate the private DNS zones when private IP addresses are allocated to a device.
