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.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。
