[Beginner] Simple Function for retrieving Local Computer IP

[AceInfinity]

I have to reset my router sometimes because internet conflicts that screw up my internet connection. When I reset the router, I get my internet back but all the computers connected to the network (ethernet) find different local IP's. Either way, if it's not practical, it's still good to understand the code to know how it retrieves your local computer IP. Most people use winsock, which is really old by now, so I thought i'd show you a different way of doing this.

educational purposes > practical use of the application
testing this code out = a sense of accomplishment
understanding the code = you've learned all you need to know here about my thread.
