一 代码

from time import sleep
from socket import gethostbyname
from datetime import datetime
def get_ipAddresses(url):
 ipAddresses=[0]
whileTrue:
 sleep(0.5)
 ip = gethostbyname(url)
if ip != ipAddresses[-1]:
 ipAddresses.append(ip)
print(str(datetime.now())[:19]+'===>'+ip)
get_ipAddresses(r'www.microsoft.com')

 

二 运行结果
