How to get all IP addresses using Python (Windows)?

I've been reading about the following solutions here, but it only works for one IP Address only. I'm not able to print the rest of the IPs (multiple network/wireless cards).

References

  1. http://net-informations.com/python/net/ipadress.htm

  2. Finding local IP addresses using Python's stdlib

  3. How do I determine all of my IP addresses when I have multiple NICs?

C:\>ipconfig | findstr IPv4
   IPv4 Address. . . . . . . . . . . : 192.168.1.1
   IPv4 Address. . . . . . . . . . . : 192.168.5.1

C:\>python
Python 3.5.1 (v3.5.1:37a07cee5969, Dec  6 2015, 01:38:48) [MSC v.1900 32 bit (Intel)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> import socket
>>> print (socket.gethostbyname(socket.gethostname()))
192.168.5.1
>>>

Please let me know how to print all IP Addresses in Python.

Update 1:

As suggested by Rahul, I've tried the following code but it didn't return anything on the screen.

c:\Python\Codes>more ip.py
from netifaces import interfaces, ifaddresses, AF_INET

def ip4_addresses():
    ip_list = []
    for interface in interfaces():
        for link in ifaddresses(interface)[AF_INET]:
            ip_list.append(link['addr'])
    return ip_list

c:\Python\Codes>

c:\Python\Codes>ip.py

c:\Python\Codes>

Update 2:

I've also tried Elemag's code as suggested here. It works on Python interpreter but not when I save the code to .py

c:\Python\Codes>python
Python 3.5.1 (v3.5.1:37a07cee5969, Dec  6 2015, 01:38:48) [MSC v.1900 32 bit (Intel)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>>
>>> [netifaces.ifaddresses(iface)[netifaces.AF_INET][0]['addr'] for iface in netifaces.interfaces() if netifaces.AF_INET in netifa
ces.ifaddresses(iface)]
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
NameError: name 'netifaces' is not defined
>>>
>>> import netifaces
>>> [netifaces.ifaddresses(iface)[netifaces.AF_INET][0]['addr'] for iface in netifaces.interfaces() if netifaces.AF_INET in netifa
ces.ifaddresses(iface)]
['192.168.1.10', '192.168.56.1', '127.0.0.1']
>>>
>>> ^Z

It's not working when I save the code into .py

c:\Python\Codes>more test.py
[netifaces.ifaddresses(iface)[netifaces.AF_INET][0]['addr'] for iface in netifaces.interfaces() if netifaces.AF_INET in netifaces.
ifaddresses(iface)]

c:\Python\Codes>test.py
Traceback (most recent call last):
  File "c:\Python\Codes\test.py", line 1, in <module>
    [netifaces.ifaddresses(iface)[netifaces.AF_INET][0]['addr'] for iface in netifaces.interfaces() if netifaces.AF_INET in netifa
ces.ifaddresses(iface)]
NameError: name 'netifaces' is not defined

c:\Python\Codes>

c:\Python\Codes>more test.py
import netifaces

I used the following example from this site as a starting point (changed to work in Python 3): https://yamakira.github.io/python-network-programming/libraries/netifaces/index.html as well as info from the module: https://pypi.org/project/netifaces/

import netifaces
for iface in netifaces.interfaces():
  iface_details = netifaces.ifaddresses(iface)
  if netifaces.AF_INET in iface_details:
    print(iface_details[netifaces.AF_INET])

which returns interface info in dictionary form:

[{'addr': '192.168.0.90', 'netmask': '255.255.255.0', 'broadcast': '192.168.0.255'}]
[{'addr': '127.0.0.1', 'netmask': '255.0.0.0', 'broadcast': '127.255.255.255'}]

as an extension to this, if you do something like:

import netifaces
for iface in netifaces.interfaces():
    iface_details = netifaces.ifaddresses(iface)
    if netifaces.AF_INET in iface_details:
        print(iface_details[netifaces.AF_INET])
        for ip_interfaces in iface_details[netifaces.AF_INET]:
            for key, ip_add in ip_interfaces.items():
                if key == 'addr' and ip_add != '127.0.0.1':
                    print(key, ip_add)

This would return your IP address in my case:

addr 192.168.0.90

Obviously, you can manipulate the dictionary as you see fit, I just added it for information sake

  • tested on windows 10 python 3.6
  • tested on linux python 2.7, 3.6

hope this helps someone
