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。
