This is a client for dynamic DNS services, aimed at ESP (ESP32, etc) devices. Your node can use such a service to make its IP address known as a public DNS name, so you can find it, and use it from applications.
An embedded HTTP server wrapping server lifecycle management, filesystem-backed static file serving, and handler registration into a small, thread-safe interface on top of the native ESP-IDF `esp_http_server` API. It is suitable for use in system services, provisioning flows, and device configuration UIs.
