python - 从我的计算机python中提取子网掩码

Question

亲爱的，我打算提取我的子网掩码，我使用了下面的代码，但子网掩码始终是 255.255.255.255，这是错误的

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()

代码的输出是:

IPAddress:  192.168.1.4
Mask:  255.255.255.255
Gateway:  192.168.1.1
IP Address:  192.168.231.1

IP Address:  127.0.0.1
Mask:  255.255.255.255
Gateway:  192.168.1.1

Answer 1

在 Windows 上有 netifaces 的替代品。您可以使用wmic检索接口(interface)信息。 wmic 有一个使用 XML 的机器可读输出选项:

wmic nic get /format:rawxml 

一个Python示例parse this output可用。
