RJUIP provides a reliable Dynamic DNS (DDNS) solution designed specifically for IoT devices, ESP8266, ESP32, and embedded systems running on dynamic IP connections.
Most IoT and embedded devices operate behind residential or mobile internet connections with frequently changing IP addresses. Without Dynamic DNS, accessing these devices remotely becomes unreliable. RJUIP DDNS automatically keeps your device hostname updated whenever the IP changes.
Simple HTTP-based update endpoints suitable for low-memory devices like ESP8266 and ESP32.
Designed for home broadband, mobile hotspots, and ISP connections with frequently changing IPs.
Secure credentials and update validation to protect your devices from unauthorized updates.
Your IoT device sends a lightweight update request to RJUIP whenever its IP address changes. Our DNS system updates the hostname instantly, ensuring continuous remote access without manual intervention.
Create your free DDNS hostname and keep your IoT devices reachable from anywhere in the world.
