How to get all ips associated with a Python domain?

Question

I need to create an application that gets all the ips associated with a domain. I tried using the following Python code:

import socket

print(socket.gethostbyname('facebook.com.br'))

However, just return me an IP. Would have some way to return the facebook range, for example?

Answer 1

Good afternoon Gurion, I think the code below may help you:

import socket

lista_de_ip = []

site = socket.getaddrinfo("www.facebook.com.br" ,0)

for i in site:
  lista_de_ip.append(i[-1][0])
lista_de_ip = list(set(lista_de_ip))

print(lista_de_ip)

Answer 2

If you prefer an option that does not use Python, you can use Tracert on Windows, or Traceroute on Linux.

Code output in Tracert

So you could use Python only to run the external command with the help of the library subprocess, instead of trying to use the resources of the language itself.

The code below executes the command and stores it in a file . txt

# coding: UTF-8


import os
import subprocess


# Se for Windows, apenas troque o traceroute por tracert
command = ['traceroute', 'www.facebook.com']

with open('log.txt', 'w') as arq:
    output_command = subprocess.call(command, stdout=arq)

print('[+] Finished')
