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

Can do the same as what they do in Python to get external IP, connect to some website and get your details from the socket connection:

const net = require('net'); const client = net.connect({port: 80, host:"google.com"}, () => {   console.log('MyIP='+client.localAddress);   console.log('MyPORT='+client.localPort); }); 

*Unfortunately cannot find the original Python Example anymore as reference..

Update 2019: Using built-in http library and public API from https://whatismyipaddress.com/api

const http = require('http');  var options = {   host: 'ipv4bot.whatismyipaddress.com',   port: 80,   path: '/' };  http.get(options, function(res) {   console.log("status: " + res.statusCode);    res.on("data", function(chunk) {     console.log("BODY: " + chunk);   }); }).on('error', function(e) {   console.log("error: " + e.message); }); 

Tested with Node.js v0.10.48 on Amazon AWS server

Update 2021
ipv4bot is closed, here is another public API:

var http = require('http');  http.get({'host': 'api.ipify.org', 'port': 80, 'path': '/'}, function(resp) {   resp.on('data', function(ip) {     console.log("My public IP address is: " + ip);   }); });

Answer 2

npm install --save public-ip from here.

Then

publicIp.v4().then(ip => {   console.log("your public ip address", ip); }); 

And if you want the local machine ip you can use this.

var ip = require("ip"); var a = ip.address(); console.log("private ip address", a);
