本文实例讲述了python实现根据ip地址反向查找主机名称的方法。分享给大家供大家参考。具体如下：

import sys, socket try: result = socket.gethostbyaddr("66.249.71.15") print "Primary hostname:" print " " + result[0] # Display the list of available addresses #that is also returned print "nAddresses:" for item in result[2]: print " " + item except socket.herror, e: print "Couldn't look up name:", e

上面的代码执行后返回：

Primary hostname: crawl-66-249-71-15.googlebot.com Addresses: 66.249.71.15

希望本文所述对大家的Python程序设计有所帮助。
