Why can't I set up an external ip for the webserver right away in NodeJS?

Question

Node.js

I have server.js web server

et http = require('http'), 
  fs = require('fs'),
  url = require('url'),
  path = require('path'),
  cmd = require('node-cmd'),
  Tail = require('tail').Tail;

let server = new http.Server(); // EventEmitter
let ip = '127.0.0.1';
let port = 8000;

server.listen(port, ip);
console.log(`server listen http://${ip}:${port} ... \n`);
server.on("connection", () => console.log("connection"));
server.on('request', (request, response) => {});

When I log in from my computer at http:// 127.0.0.1:8000
Everything works
However, I'm connected to an external network, why when I connect via external ip http

:// 10.1.4.58:8000, I see a similar picture

set up a web server so that it can use my local ip on its external ip? Or how to write the web server config in general?

Good afternoon.
Painful to read:
Let's first read this: https://ru.wikipedia.org/wiki/%D0%A7%D0%B0%D1%81%D...
Then you will think about what "interfaces" are.
Then you think about what 0.0.0.0 is and what people use it for.
And then ask the question again.
