TM4C129 LaunchPad dynamically changing the IP address

[lilyhack 3]

I am using TM4C129 LaunchPad for an Industrial IoT product. We want to have a web server running on it.

 

I am looking into this example of setting up the IP address. To do it this way, every time you join a new network, you have to change the code for a different IP address. Is there a way to avoid this problem? Any example of how can I change the IP address automatically as soon as it joins a a new network? 

 

I believe that the TivaWare provided example enet_io for the TM4C129x board does what I am looking for. But I would like an example in Energia. Can you please help?
