查询本机内网IP地址-ifconfig

这里的eth0 的 inet 的值 172.14.116.91 即使内网ip。

[root@htlwk0001host ~]# ifconfig
eth0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
        inet 172.14.116.91  netmask 255.255.240.0  broadcast 172.14.127.255

        inet 127.0.0.1  netmask 255.0.0.0

[root@htlwk0001host ~]# ifconfig eth0
eth0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500

说明

  1. eth0:是指第一个物理网卡,具体叫光纤以太网接口卡,学名 Fiber Ethernet Adapter0。物理网卡这里指的是服务器上实际的网络接口设备,这里我服务器上双网卡,在系统中看到多个物理网卡则分别对应 eth0、eth1、eth2…,类似 Windows 装了好几个网卡,会显示本地连接1、本地连接2、本地连接3…
  2. lo:localhost 本地连接,127.0.0.1。
  3. en0:en0 是逻辑上的网络接口名,enx(x是一个数字,代表第几块网卡)是标准以太网接口,ent0 是物理设备,en0 是逻辑设备。查看网络接口信息时,假设看到三个网络接口,en0, en1, en2,但是只有 en1 的状态是 Available 的,说明目前只有这个口已经插上网线在使用,而其它的并没有在用。
