Hi to all I have developed a project with arm Cortex m-3 (LPC series) equipted with tcp/ip and i connected a modem router to it with CAT5 cable .When I would like to connect to my device from another city I must buy and set the Static ip address on the router and do port forwarding to access to my device.i want to send microcontroller public ip address to the web service every time the device is reset or turn on. Does any one know how can i use Dynamic DNS in my microcontroller and give me a light on this way in oredr to decrease the price of project via removing static ip address?
yes. i have the same question. can you post all knowledge about how the public ip address is used with cortex m3.
Again, this has nothing to do with Cortex-M3 or Keil.
The whole point of the internet is that it uses standard protocols which work and are used in exactly the same way by all equipment - they do not differ or depend on what particular processor you are using.
So you need to consult standard TCP/IP networking books & resources ...
