How would the outside world access my machine? [closed]

Question

I have a local address e.g:

http://127.0.0.1:8125/ -> this works,

How would I access this using a different PC lets say from work, or friends house or allow anyone to access this?

I am using node.js to create a simple server and listens for the above port on that local IP

any help would be appriciated.

Answer 1

You need, at a bare minimum:

1. A public IP address

2. Whatever port your app runs on open on that IP

This will allow you to browse to your page by typing the public IP and port number into the address bar of a browser.

Realistically, you need:

1. A static public IP address

2. Whatever port your app runs on open on that IP

3. Register a domain name

4. Have one or more (at least 2 is best practice) DNS servers that hold an authoritative copy of your zone.

This will allow your application to be accessed by typing: http://whatever.tld. If you use a non-standard port (I.E not 80 or 443) you'll need to append the port number at the end of the address following a colon.

Answer 2

You need an Dynamic Host like dyndns. If you have an Hostname you configure and port forwarding in your router to your workstation and you can access it from every point of the whole internet :)
