解决GitHub无法访问
一、访问github
1、方案一：固定修改hosts（不推荐，访问慢）
win7的hosts文件中：
C:\Windows\System32\drivers\etc\hosts
追加如下内容：
# Github Hosts # Update 20211204 # domain: github.com 140.82.114.4 github.com 140.82.114.10 nodeload.github.com 140.82.114.6 api.github.com 140.82.114.10 codeload.github.com 185.199.108.133 raw.github.com 185.199.108.153 training.github.com 185.199.108.153 assets-cdn.github.com 185.199.108.153 documentcloud.github.com 185.199.108.154 help.github.com # domain: githubstatus.com 185.199.108.153 githubstatus.com # domain: fastly.net 199.232.69.194 github.global.ssl.fastly.net # domain: githubusercontent.com 185.199.108.133 raw.githubusercontent.com 185.199.108.154 pkg-containers.githubusercontent.com 185.199.108.133 cloud.githubusercontent.com 185.199.108.133 gist.githubusercontent.com 185.199.108.133 marketplace-screenshots.githubusercontent.com 185.199.108.133 repository-images.githubusercontent.com 185.199.108.133 user-images.githubusercontent.com 185.199.108.133 desktop.githubusercontent.com 185.199.108.133 avatars.githubusercontent.com 185.199.108.133 avatars0.githubusercontent.com 185.199.108.133 avatars1.githubusercontent.com 185.199.108.133 avatars2.githubusercontent.com 185.199.108.133 avatars3.githubusercontent.com 185.199.108.133 avatars4.githubusercontent.com 185.199.108.133 avatars5.githubusercontent.com 185.199.108.133 avatars6.githubusercontent.com 185.199.108.133 avatars7.githubusercontent.com 185.199.108.133 avatars8.githubusercontent.com # End of the section

2、方案二：动态修改hosts（强烈推荐，访问快）
获取github.global.ssl.fastly.net的IP：如，199.232.69.194
https://ipaddress.com/website/github.global.ssl.fastly.net#ipinfo、
获取github.com的IP：如，140.82.112.3
https://ipaddress.com/website/github.com#ipinfo
199.232.69.194 github.global.ssl.fastly.net
140.82.112.3 github.com
