使用Python进行DNS查询

最近，实验室布置一个简单的任务，对学校官网www.hitwh.edu.cn进行DNS查询
要求使用python，既然布置了，那就做做呗。
1.pyDNS库
在linux上用python3装pyDNS总是会出现问题，所以放弃了python3，最后总算是用python2装好了pyDNS库

>>>improt DNS>>>

import成功了，这是第一步
下面开始写代码

!/usr/bin/env python Basiv DNS library example - Chapter 4   DNS-basic.pyimport sysimport DNSimport timequery = sys.argv[0]DNS.DiscoverNameServers()reqobj = DNS.Request("www.hitwh.edu.cn")answerobj = reqobj.req(name = query, qtype = DNS.Type.A)if not len(answerobj.answers):    print ("Not found.")for item in answerobj.answers:    print ("%-5s %s" % (item['typename'], item['data']))reqobj0 = DNS.Request("hitwh.edu.cn")answerobj = reqobj0.req(name = query, qtype = DNS.Type.ANY)if not len(answerobj.answers):    print ("Not found.")for item in answerobj.answers:    print ("%-5s %s" % (item['typename'], item['data']))    print ("WHEN:",    time.asctime(time.localtime(time.time())))

得到的结果如图所示：
