python实现根据ip地址反向查找主机名称的方法

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测试数据

Addresses:
 66.249.71.15 

希望本文所述对大家的Python程序设计有所帮助。
