折腾：
期间，想要了解此处买到的百度的云服务器的CentOS中的内网IP和外网IP
再去搜：
centos 查看ip
参考：
CentOS 查看IP,端口 修改IP,打开端口生效 – lhj588 – 博客园
去试试：
[root@instance-jb4q99qd ~]# ifconfig | grep broadcast
inet 192.168.0.4 netmask 255.255.240.0 broadcast 192.168.15.255
[root@instance-jb4q99qd ~]#
[root@instance-jb4q99qd ~]# ifconfig -a

[root@instance-jb4q99qd ~]# curl ifconfig.me
106.12.26.141
另外，本地电脑直接打开：
What Is My IP Address? – ifconfig.me
也可以看到类似信息：
所以再去BCC主机中试试其他命令：
[root@instance-jb4q99qd ~]# curl ifconfig.me
106.12.26.141
[root@instance-jb4q99qd ~]# curl ifconfig.me/host
[root@instance-jb4q99qd ~]# curl ifconfig.me/ua
curl/7.29.0
[root@instance-jb4q99qd ~]# curl ifconfig.me/port

[root@instance-jb4q99qd ~]# curl ifconfig.me/lang
[root@instance-jb4q99qd ~]# curl ifconfig.me/mime

【总结】
CentOS 7中查看当前主机：
内网IP：
ifconfig -a
输出结果中的broadcast的部分
此处结果是：192.168.15.255
外网IP：通过访问别的查询网站而获得当前的外网IP，比如：
curl ifconfig.me
或：curl icanhazip.com
此处结果是：106.12.26.141
