问题描述
我已经编辑了我的 /etc/hosts 文件，如下所示。我是 mac Os 的新手，并尝试运行一些代码并进行测试。为此，我必须编辑 /etc/hosts 文件。但是 ping 的 IP 没有按预期工作。请帮助我理解这个问题。
# Host Database
#
# localhost is used to configure the loopback interface
# when the system is booting. Do not change this entry.
##
127.0.0.1 localhost
255.255.255.255 broadcasthost
::1 localhost
127.0.0.1 198.18.0.98
127.0.0.1 70.70.70.70
127.0.0.1 nipuna.lk
# Added by Docker Desktop
# To allow the same kube context to work on the host and the container:
127.0.0.1 kubernetes.docker.internal
# End of section
ping nipuna.lk 工作正常。 ping 70.70.70.70 需要 300-400 毫秒，但 ping 有效。但 ping 198.18.0.98 不起作用。我不知道为什么会这样。
我的防火墙已关闭。
