我 ping 服务器的地址是可以 ping 通的，就是域名不通
所以我怀疑是 dns 解析问题，我修改了 dns 也没用

➜ ~ networksetup -setdnsservers Wi-Fi 8.8.8.8
➜ ~ ping dev
ping: cannot resolve dev: Unknown host
➜ ~ networksetup -setdnsservers Wi-Fi 202.106.0.20
➜ ~ ping dev
ping: cannot resolve dev: Unknown host
➜ ~ networksetup -setdnsservers WiFi 219.141.140.10
WiFi is not a recognized network service.
** Error: The parameters were not valid.
➜ ~ networksetup -setdnsservers Wi-Fi 219.141.140.10
➜ ~ ping dev
ping: cannot resolve dev: Unknown host

服务器那边的映射域名是这样的

10.31.84.241 dev
118.190.142.247 stephen-dev

我同事是可以 ping 通的，就我的 mac 连不通，求人指教，谢谢
