I'm developing an app/server. The server is running locally on my laptop. At home I look at network utility (Im on OS X) which gives my laptop's local ip address. On my phone I tell the app to connect to that ip for testing. This works fine. Usually addresses are 192.168.0.40 or something like this.
But today Im in a (big) public library, with lots of people using the free Wi-Fi. The above process to connect doesn't work; My computer's local ip looks more complicated (10.177.53.216). Is there a way to connect the devices?
