我们查看 ifconfig

bash 复制代码

[zk@VM-24-17-centos ~]$ ifconfig
eth0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
        inet 10.0.24.17  netmask 255.255.252.0  broadcast 10.0.27.255
        inet6 fe80::5054:ff:fe3a:de5c  prefixlen 64  scopeid 0x20<link>

这里有一个ip地址，是内网IP

bash 复制代码

10.0.24.17

但是我们登录腾讯云的ip地址跟这个完全不一样

类似于

cpp 复制代码

119.29.219.xxx

我们跨主机想使用upd进行通信的时候，用的是下面这个ip。后面详细讲
