Dynamic DNS Using an Arduino

DDNS is a service use to access a device to your home and to avoid your ISP to dynamically assign a new IP address.

This device allows a remote access your LAN address even if the IP address connection changed. As the provider cannot assign a certain IP address to all of their users; some of the users work with Dynamic IP in order to make a connection to their modem or router. This made the other user’s connection being closed, now it is impossible to contact any device connected to LAN Internet.

Their device is made from a circuit of an Ethernet Interface WIZnet WIZ811MJ with an Atmega328 microcontroller programmed with Arduino bootloader. With the Atmega I/O PB2, PB3, PB4 and PB5, they are dedicated to dialogue with the Ethernet module and provide a full wire SPI bus. The microcontroller is programmed using the special interface TTL / USB from SparkFun. Once you are ready to the process, you can now go to the site in order to provide you the session that will send you data like the user name and password, string that contains your current IP connection.
