A Python script must retrieve the netmask for each IPv4 address on a Windows machine. The script can use third-party libraries. Which code snippet correctly retrieves the netmask?

import socket; print(socket.inet_ntoa(socket.inet_aton('255.255.255.0')))

import uuid; print(uuid.getnode())

import psutil; for name, addrs in psutil.net_if_addrs().items(): for addr in addrs: if addr.family == socket.AF_INET: print(addr.netmask)

import os; print(os.popen('ipconfig').read())

Which netifaces function retrieves a dictionary of address families and associated addresses for a specific network interface?

netifaces.ifaddresses(interface)

A network administrator wants to write a Python script that prints the MAC address of the primary Ethernet interface on a Linux server. The script will be run manually by administrators and can use third-party libraries. Which code snippet accomplishes this?

import socket; print(socket.gethostbyname('eth0'))

import psutil; addrs = psutil.net_if_addrs()['eth0']; print(addrs[0].address)

import fcntl, socket; print(socket.inet_ntoa(fcntl.ioctl(socket.socket(socket.AF_INET, socket.SOCK_DGRAM), 0x8927, b'eth0')[20:24]))

import uuid; print(uuid.getnode())
