The main core of DNS resolving is the resolver . This class wraps queries into DNS packets and sends them to any DNS server. The response is then decoded into some useful information (at least for programmers, or for me in special -)). All my DNS stuff uses the namespace Heijden.DNS. Don t change it in your applications, it gives me some comfort knowing my name is stored in some nice other projects. Don t forget to let me know. Because I don t want to go immediately into details in this article, I only show the usage of the resolver component to warm you up. As the best way to do this, I have built a Dig class which acts like the good-old-Unix-style dig. Its acts like dig, but it is not a complete dig implementation. It does, however, do everything you want it to, presenting the output in more or less the same format. This is the outline of the Dig class:

这段代码是一个 Python 程序，实现了一个 MDNS 服务。MDNS 是一种局域网内的服务发现协议，它允许设备在局域网内自动发现和连接到其他设备提供的服务。这个程序使用了 Python 的 socket 和 dns.resolver 模块，创建了一个 UDP 套接字并绑定到 MDNS 服务器的 IP 地址和端口号。然后程序不断监听 MDNS 请求，当收到请求时，解析 DNS 查询并向请求者发送一个 HTTP 响应，该响应包含一个简单的 "Hello, world!" 页面。最后，程序关闭了套接字。
