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

My shameless plug: canihazip (Disclosure: I'm the author of module, but not of the main page.)

It can be required as a module, exposing a single function that can optionally be passed a callback function an it will return a promise.

It can be also be installed globally and used as CLI.

Answer 2

use externalip package

https://github.com/alsotang/externalip

externalip(function (err, ip) {
  console.log(ip); // => 8.8.8.8
});

Answer 3

You may use the request-ip package:

const requestIp = require('request-ip');

// inside middleware handler
const ipMiddleware = function(req, res, next) {
    const clientIp = requestIp.getClientIp(req); 
    next();
};

Answer 4

You can use nurl library command ippublic to get this. (disclosure: I made nurl)

> npm install nurl-cli -g
> ippublic;
// 50.240.33.6

Answer 5

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);

Answer 6

I was looking for a solution not relying to other's libraries/ resources, and found this as acceptable alternative:

Just a GET request to external server ( under my control ), where I read req.headers['x-forwarded-for'] and serve it back to my client.
