笔记本电脑打开Github有时候图片加载不出来，而台式机则没有这个问题。Chrome浏览器F12进入Network标签，然后Disable cache之后刷新页面，发现是几个avatars5.githubusercontent.com之类的网页资源加载失败了。
最简单的解决办法是打开IPAddress.com找到对应的ip地址，然后加入hosts文件。但是由于不止一个网址失败，这里我想要找到一个更自动化的解决办法。
参考Github520项目，解决办法有以下几种：
- 手动修改hosts文件
- SwitchHosts自动管理
- AdGuard Home自动管理DNS
手动修改hosts文件
