连不上GitHub,也ping不通,亲测解决方案
1.打开hosts文件,C:\Windows\System32\drivers\etc
2.在最后一行添加如下地址
192.30.253.113 github.com
192.30.252.131 github.com
185.31.16.185 github.global.ssl.fastly.net
74.125.237.1 dl-ssl.google.com
173.194.127.200 groups.google.com
192.30.252.131 github.com
185.31.16.185 github.global.ssl.fastly.net
74.125.128.95 ajax.googleapis.com
保存后再ping一下,完全没毛病!
