A Simple Public IP Address API

Introduction

This repository contains the Python script which you can use to run on Azure Functions to obtain your public IPv4 address. The code is stored in one file, which uses HTTP X-Forwarded-For header for IP identifying.

Full instruction how exactly this code is working is available here

Demo

You can get an output in a different formats. List of currently available formats are stored in the table below:

API URL	Response Type	Sample Output (IPv4)
https://showip.azurewebsites.net/api/http	text	1.2.3.4
https://showip.azurewebsites.net/api/http?format=json	json	{"ip":"1.2.3.46"}
https://showip.azurewebsites.net/api/http?format=jsonp	jsonp	callback({"ip":"1.2.3.4"});

Code examples

This section contains some common usage patterns from a variety of programming languages.

Bash

#!/bin/bash

ip=$(curl -s https://showip.azurewebsites.net/api/http)
echo "My public IP address is: $ip"

NGS (Next Generation Shell)

ip=`curl -s https://showip.azurewebsites.net/api/http`
echo("My public IP address is: $ip")

Python

# This example requires the requests library be installed.  You can learn more
# about the Requests library here: http://docs.python-requests.org/en/latest/
from requests import get

ip = get('https://showip.azurewebsites.net/api/http').text
print('My public IP address is: {}'.format(ip))

Ruby

require "net/http"

ip = Net::HTTP.get(URI("https://showip.azurewebsites.net/api/http"))
puts "My public IP Address is: " + ip

PHP

<?php
    $ip = file_get_contents('https://showip.azurewebsites.net/api/http');
    echo "My public IP address is: " . $ip;
?>

Java

try (java.util.Scanner s = new java.util.Scanner(new java.net.URL("https://showip.azurewebsites.net/api/http").openStream(), "UTF-8").useDelimiter("\\A")) {
    System.out.println("My current IP address is " + s.next());
} catch (java.io.IOException e) {
    e.printStackTrace();
}

Perl

use strict;
use warnings;
use LWP::UserAgent;

my $ua = new LWP::UserAgent();
my $ip = $ua->get('https://showip.azurewebsites.net/api/http')->content;
print 'My public IP address is: '. $ip;

C#

var httpClient = new HttpClient();
var ip = await httpClient.GetStringAsync("https://showip.azurewebsites.net/api/http");
Console.WriteLine($"My public IP address is: {ip}");

VB.NET

Dim httpClient As New System.Net.Http.HttpClient
Dim ip As String = Await httpClient.GetStringAsync("https://showip.azurewebsites.net/api/http")
Console.WriteLine($"My public IP address is: {ip}")

Go

package main

import (
        "io/ioutil"
        "net/http"
        "os"
)

func main() {
        res, _ := http.Get("https://showip.azurewebsites.net/api/http")
        ip, _ := ioutil.ReadAll(res.Body)
        os.Stdout.Write(ip)
}

Racket

(require net/url)

(define ip (port->string (get-pure-port (string->url "https://showip.azurewebsites.net/api/http"))))
(printf "My public IP address is: ~a" ip)

Lisp

;This example requires the drakma http package installed.
;It can be found here: http://www.weitz.de/drakma

(let ((stream
    (drakma:http-request "https://showip.azurewebsites.net/api/http" :want-stream t)))
  (let ((public-ip (read-line stream)))
    (format t "My public IP address is: ~A" public-ip)))

Xojo

Dim s As New HTTPSecureSocket
Dim t As String = s.Get("https://showip.azurewebsites.net/api/http",10)
MsgBox "My public IP Address is: " + t

Scala

val addr = scala.io.Source.fromURL("https://showip.azurewebsites.net/api/http").mkString
println(s"My public IP address is: $addr")

Javascript

<script type="application/javascript">
  function getIP(json) {
    document.write("My public IP address is: ", json.ip);
  }
</script>

<script type="application/javascript" src="https://showip.azurewebsites.net/api/http?format=jsonp&callback=getIP"></script>

jQuery

<script type="application/javascript">
  $(function() {
    $.getJSON("https://showip.azurewebsites.net/api/http?format=jsonp&callback=?",
      function(json) {
        document.write("My public IP address is: ", json.ip);
      }
    );
  });
</script>

using System;
using System.Net;

namespace PublicIP.Examples {
    class Program {
        public static void Main (string[] args) {
            WebClient webClient = new WebClient();
            string publicIp = webClient.DownloadString("https://showip.azurewebsites.net/api/http");
            Console.WriteLine("My public IP Address is: {0}", publicIp);
        }
    }
