作為一名程序員，在國內訪問GitHub官網經常會遇到打開過慢或者訪問失敗的問題，但通過一些技巧可以改善訪問體驗。GitHub訪問問題的根源在于GitHub官網訪問不穩定的主要原因在于DNS解析過程。當我們直接訪問github.com時，需要通過DNS服務器將域名轉換為對應的IP地址。由于某些原因，這個解析過程在國內可能會變得緩慢或不穩定，導致有時能打開，有時無法訪問，或者加載速度極慢。本文通過介紹修改Hosts文件解決GitHub訪問過慢或者打不開的為標題
1.打開dns查詢 - bejson在線工具，輸入“https://github.com” 解析域名
2.修改C:\Windows\System32\drivers\etc下的hosts文件
3.啟動命令運行窗口，運行命令：ipconfig/flushdns ，刷新DNS緩存。
4.驗證配置是否生效，命令運行窗口，運行命令：ping github.com，如下圖說明配置成功
5.瀏覽器訪問https://github.com/可以正常訪問，如無法訪問可以重啟電腦試試
6.下面是git相關的域名和DNS解析，也可訪問https://raw.hellogithub.com/hosts直接下載
