作为一名程序员，在国内访问GitHub官网经常会遇到打开过慢或者访问失败的问题，但通过一些技巧可以改善访问体验。GitHub访问问题的根源在于GitHub官网访问不稳定的主要原因在于DNS解析过程。当我们直接访问github.com时，需要通过DNS服务器将域名转换为对应的IP地址。由于某些原因，这个解析过程在国内可能会变得缓慢或不稳定，导致有时能打开，有时无法访问，或者加载速度极慢。本文通过介绍修改Hosts文件解决GitHub访问过慢或者打不开的为标题
1.打开dns查询 - bejson在线工具，输入“https://github.com” 解析域名
2.修改C:\Windows\System32\drivers\etc下的hosts文件
3.启动命令运行窗口，运行命令：ipconfig/flushdns ，刷新DNS缓存。
4.验证配置是否生效，命令运行窗口，运行命令：ping github.com，如下图说明配置成功
5.浏览器访问https://github.com/可以正常访问，如无法访问可以重启电脑试试
6.下面是git相关的域名和DNS解析，也可访问https://raw.hellogithub.com/hosts直接下载
