When you start web2py, the console will always display:
But if you started it with "-i 0.0.0.0", it will be accessible from any device on your internal network. To access the app from devices on your internal network, you will need to know the internal IP address of your computer, which will have been assigned by your router. It will probably be something like 192.168.0.xxx or 10.0.0.xxx.
Are you trying to make the app accessible publicly from the internet as well (i.e., from devices outside your local network)? In that case, you will probably need to configure your router to accept incoming connections over port 80 (or 8000 or some other port if you prefer), and tell it to route such incoming connections to the internal IP address of your computer.
Is this just for testing purposes, or are you expecting to host a public website from your computer?
