Dears I was planning to extract my Subnet mask, I had used the below code but the subnetmask is always 255.255.255.255 which is wrong 

import socket               # Import socket module
import netifaces

def get_ip_address():
    s = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
    s.connect(("8.8.8.8", 80))
    My_ip=s.getsockname()[0]
    s.close()
    return My_ip

def main():
    #print(netifaces.interfaces())

    for i in netifaces.interfaces():
        try:
            # Address
            print("IP Address: ", netifaces.ifaddresses(i)[netifaces.AF_INET][0]['addr'])
            print("Mask: ", netifaces.ifaddresses(i)[netifaces.AF_INET][0]['netmask'])
            print("Gateway: ", netifaces.gateways()['default'][netifaces.AF_INET][0])

        except:pass

# This is the IP address of the GateWay

if __name__ == '__main__': main()

The output of the code is:

IPAddress:  192.168.1.4
Mask:  255.255.255.255
Gateway:  192.168.1.1
IP Address:  192.168.231.1
Mask:  255.255.255.255
Gateway:  192.168.1.1
IP Address:  192.168.116.1
Mask:  255.255.255.255
Gateway:  192.168.1.1
IP Address:  10.255.90.137
Mask:  255.255.255.255
Gateway:  192.168.1.1
IP Address:  127.0.0.1
Mask:  255.255.255.255
Gateway:  192.168.1.1

The output of the IPconfig/all on the CMD:

ipconfig /all

There are alternatives to netifaces on Windows. You can retrieve the interface information using wmic. wmic has a machine readable output option using XML:

wmic nic get /format:rawxml

A python example to parse this output is available.
