1.进入网站测试ip地址
https://ip.tool.chinaz.com/github.com
2.对windows获取到的ip复制到C:\Windows\System32\drivers\etc
ubuntu复制到sudo vim /etc/hosts
3.在底部加入对应的ip地址
185.199.109.153 assets-cdn.github.com
185.199.110.153 assets-cdn.github.com
185.199.111.153 assets-cdn.github.com
4.Windows修改完映射文件，打开cmd输入ipconfig/flushdns刷新dns缓存。Linux也需要刷新dns,以ubuntu为例，sudo /etc/init.d/networking restart
5.重启浏览器
