What IP should I used when trying to establish a connection as the server?

IP.get_local_interfaces() returns the above results

Also please don't mind the fact that I censored 127.0.0.1, I'm dumb

I haven't been ambitious enough to try what you're attempting now.

I AM tempted to try, though. I might try it after I finish the current project I'm working on.
