How do I listen for HTTP requests from the internet? (lemmy.ca)

I've been able to set up sending and listening to http requests locally using 127.0.0.1:8000. I want to try doing it using the internet now.

I have a VPN with port forwarding enabled, but sending requests to that IP address and port does not yield a response like it did when doing it locally.

Can anyone clarify which address I should be listening on in order to receive http requests from the internet? I tried 0.0.0.0 and a few inet addresses from ip add, but none of them work.

You don’t normally “listen” on an IP address

You can bind to an IP when you open a port, it lets you limit your listening to a particular device if there are more than one interfaces. 0.0.0.0 means to listen on "all available" devices.

Yeah I guess that fits their explanation, but I still don't get what they are trying to do.
