DDNS_Generic

A simple library that implements an automatic DDNS Update Client for SAM DUE, nRF52, SAMD21/SAMD51, STM32F/L/H/G/WB/MP1, etc. besides ESP8266/ESP32, using ESP8266-AT/ESP32-AT WiFi, WiFiNINA, Ethernet W5x00, ENC28J60 or LAN8742A. It is designed to be light-weight and currently supports DuckDNS, No-ip, DynDNS, Dynu, enom, all-inkl, selfhost.de, dy…

Why do we need this DDNS_Generic library

Many of us are using Dynamic DNS service because Dynamic IP addresses is much cheaper than the expensive static IP address.

Dynamic IP addresses present a problem if we wants to provide a service to other users on the Internet, such as a web service, Blynk Local Server, etc. As the IP address may change frequently (due to power outtage/surge, power on/off, DSL/Fiber issues, etc.), the corresponding domain names must be quickly re-mapped in the DNS, to maintain accessibility using a well-known URL.

Many providers offer commercial or free Dynamic DNS service for this scenario. The automatic reconfiguration is generally implemented in the user’s router or computer, which runs software to update the DDNS service. The communication between the user’s equipment and the provider is not standardized, although a few standard web-based methods of updating have emerged over time.

This Library is created to automatically update your DDNS Domains with the latest dynamic IP address, using one of the many available boards / shields. See Currently Supported Boards.

The time between checks to update the DDNS Service is configurable to match your use case, and is set in the examples at 10 minutes.

The DDNS_Generic code is very short, can be immersed in your Projects and to be called in the loop() code.

It currently supports DuckDNS, No-ip, DynDNS, Dynu, enom, all-inkl, selfhost.de, dyndns.it, strato, freemyip, afraid.org. Expansion to support more DDNS sevice providers is very easy and can be done by yourself.
