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.
