Dig+trace

前几天我增加了一个小工具：Dig+trace域名查询工具，可用于域名解析诊断，今天顺便同大家分享一下域名解析的过程，一起探究一下域名解析的原理，什么是域名我相信各位看官已经不用介绍了，我们直接从域名解析过程开始。

首先，计算机拿到用户输入的域名以后会去查询一个服务器，那就是咱们电脑中设置的DNS服务器，DNS是指 Domain Name System，每个运营商都会提供一个DNS服务器来供用户解析域名，本文不讲DNS的原理，只讲域名的解析过程，所以直接看解析的过程。

以 www.renfei.net 为例，以英文点“.”为界限，会被分为以下几个部分：

.：根net.：顶级域名renfei.net.；一级域名www.renfei.net.：二级域名

解析过程：
