Feature Request: Device-Specific DNS Offline Alerts (Integrated Monitoring with ControlD DDNS)

Hello ControlD Team,

I would like to suggest a feature that would be extremely useful for users who rely on ControlD for both DNS and DDNS.

Feature idea:
Allow us to enable offline alerts for specific devices that are assigned to a custom DNS profile. For example, if I assign a dedicated ControlD DNS resolver to a router or server, I would like to receive a notification (email or push alert) when that device becomes unreachable/offline.

Why this matters:

Currently, most common routers do not support third-party monitoring services combined with DDNS.
By having this functionality directly in ControlD, we could avoid using external uptime services.
It would create a seamless integration between ControlD DDNS and DNS, making it easier to monitor the availability of key devices (e.g., routers, servers, IoT gateways).

Suggested options:

Enable/disable alerts per device/DNS profile.
Choose notification type: email, webhook, push.
Simple dashboard view to check device availability history.

This would save us from relying on external tools and make ControlD a more complete solution for users managing their own networks.

Thank you for considering this!
