How to get my external IP address with node.js?

Question

I\'m using node.js and I need to get my external IP address, provided by my ISP. Is there a way to achieve this without using a service like http://myexternalip.com/raw ?

Answer 1

You could very easily use an api solution for retrieving the external IP! I made a ip tracker site made for this kinda thing a few days ago! Here is a snippit of code you could use to get IP!

async function getIp(cb) {
    let output = null;
    let promise = new Promise(resolve => {
        let http = new XMLHttpRequest();
        http.onreadystatechange = function() {
            if (this.readyState == 4 && this.status == 200) {
                output = this.responseText;
                resolve("done");
            }
        }
        http.open("GET", "https://iptrackerz.herokuapp.com/ip", true);
        http.send();
   });
  await promise;
  if (cb != undefined) {
      cb(JSON.parse(output)["ip"]);
  } else {
      return JSON.parse(output)["ip"];
  }
}

Ok, now you have the function getIp()! The way I coded it allows you to do 2 different ways of invoking it! Here they are.

1. Asynchronous

   async function printIP() { let ip = await getIp(); document.write("Your IP is " + ip); }; printIP();

2. Callback

   getIp(ip => { document.write("Your IP is " + ip); });

Answer 2

this should work well without any external dependencies (with the exception of ipify.org):

var https = require('https');

var callback = function(err, ip){
    if(err){
        return console.log(err);
    }
    console.log('Our public IP is', ip);
    // do something here with the IP address
};

https.get({
    host: 'api.ipify.org',
}, function(response) {
    var ip = '';
    response.on('data', function(d) {
        ip += d;
    });
    response.on('end', function() {
        if(ip){
            callback(null, ip);
        } else {
            callback('could not get public ip address :(');
        }
    });
});

You could also use https://httpbin.org

GET https://httpbin.org/ip
