dnspython 一个Python实现的一个DNS工具包，利用其查询功能来实现dns的服务监控及解析结果的校验。 安装 pip install dnspython 解析域名为IP from dns import resolver f = open('ddd.log', 'w') with open('urls.txt', 'r') as fp: for line in fp: try: url = line[7:].strip() ans = resolver.query(url, 'A') # A记录，将主机名转换为IP地址； # for x in ans.response.answer: # 获取结果 # for y in x.items: # print(y) t = url + '||Successful!' except Exception as e: t = url + '||' + str(e) print('resolver error!') finally: f.write(t + '\n') f.close() urls.txt http://www.lyskjqbyjs.cn http://www.haict.edu.cn http://news.kf.cn http://www.henanjubao.com http://huixiangtan.smx

Python的dnspython库使用指南

　　因为平时在测试DNS的时候有些操作手动完成不方便，所以需要用到脚本，而在Python里dnspython这个用于DNS操作的库十分强大，但是无奈网上大部分资料只列举了少部分的用法，所以记录一下我平时使用到的功能，基本上已经能应付大部分的使用场景了。想具体了解dnspython可以登录 官方网站 阅读使用文档. 常用工具 最常用的用法是调用默认的resolver发送解析请求，如 from dns import resolver ans = resolver.query( " www.baidu.com " , " A " ) print ( " qname: " ,ans.qname) print ( " reclass: " ,ans.rdclass) print ( " rdtype: " ,ans.rdtype) print ( " rrset: " ,ans.rrset) print ( " response: " ,ans.response) 结果为 ( ' qname: ' , <DNS name www.baidu.com.> ) ( ' reclass: ' , 1 ) ( ' rdtype: ' , 1 ) ( ' rrset: ' , <DNS www.a.shifen.com. IN A RRset> ) ( ' response: ' , <DNS

简介 dnspython – 是python实现的一个DNS工具包，利用其查询功能来实现dns的服务监控及解析结果的校验 安装dnspython pip install dnspython 使用 常见的DNS解析类型包括A、MX、NS、CNAME （1）A记录的查询，实例如下： import dns.resolver domain = raw_input('Please input an domain: ') A = dns.resolver.query(domain, 'A') for i in A.response.answer: for j in i.items: print j.address 运行输入：www.baidu.com,输出结果如下： （2）MX记录 domain = raw_input('Please input an domain: ') MX = dns.resolver.query(domain, 'MX') for i in MX: print 'MX preference =', i.preference, 'mail exchanger =', i.exchange 运行输入：163.com,输出结果如下： （3）NS记录 print '*************NS****************' domain = raw_input(

python实现dns查询

dnspython模块中最常用的域名查询，它提供了一个DNS解析器类–resolver，使用resolver的query方法来实现域名的查询功能。 1.模块库安装 pip install dnspython 2.指定DNS服务器 my_resolver = dns.resolver.Resolver() my_resolver.nameservers = [DNS_Server] 3.query方法的定义 query（self,qname,rdtype=1,rdclass=1,tcp=False,source=None,raise_on_no_answer=True, source_port=0） 参数说明： qname表示待查询的域名，例如：www.baidu.com； rdtype用来指定待查询的类型，如A记录、MX记录、NS记录等； rdclass用来指定网络类型，如IN、CH、HS等，默认为IN； tcp用来指定查询时是否使用TCP协议，默认为False(即使用UDP)； source和source_port用于指定查询源地址与端口，默认为查询设备IP和0端口raise_on_no_answer用来指定当查询无应答时是否触发异常。 4.代码实现 #!/usr/bin/env python # -*- coding: UTF-8 -*- #说明1

Tell urllib2 to use custom DNS

由 六月ゝ 毕业季﹏ 提交于 2019-12-17 07:15:18
问题 I'd like to tell urllib2.urlopen (or a custom opener ) to use 127.0.0.1 (or ::1 ) to resolve addresses. I wouldn't change my /etc/resolv.conf , however. One possible solution is to use a tool like dnspython to query addresses and httplib to build a custom url opener. I'd prefer telling urlopen to use a custom nameserver though. Any suggestions? 回答1: Looks like name resolution is ultimately handled by socket.create_connection . -> urllib2.urlopen -> httplib.HTTPConnection -> socket.create

How do we get TXT, CNAME and SOA records from dnspython?

问题 I have a requirement to have a dns query function to query a server for various records. I figured out how to get the MX record (most of the examples show this), A record and NS record. How do I get the TXT, CNAME and SOA records? Sample code snippet: import dns.resolver answer=dns.resolver.query("google.com", "A") for data in answer: print data.address I tried replacing the query type with TXT and the data.address object with data.text, data.data etc, but ended up with attribute errors.
