linux命令之查看ip地址

一、使用ifconfig查看。

ms@ubuntu:~$ ifconfig
ens33: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
        inet 198.168.1.20  netmask 255.255.255.0  broadcast 198.168.1.255
        inet6 fe80::2de:7698:61b8:808a  prefixlen 64  scopeid 0x20<link>
        ether 00:0c:29:9b:91:81  txqueuelen 1000  (Ethernet)
        RX packets 10685  bytes 13517174 (13.5 MB)
        RX errors 0  dropped 0  overruns 0  frame 0
        TX packets 5727  bytes 421591 (421.5 KB)
        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0

lo: flags=73<UP,LOOPBACK,RUNNING>  mtu 65536
        inet 127.0.0.1  netmask 255.0.0.0
        inet6 ::1  prefixlen 128  scopeid 0x10<host>
        loop  txqueuelen 1000  (Local Loopback)
        RX packets 508  bytes 40283 (40.2 KB)
        RX errors 0  dropped 0  overruns 0  frame 0
        TX packets 508  bytes 40283 (40.2 KB)
        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0

ms@ubuntu:~$

二、使用ip a查看。

ms@ubuntu:~$ ip a
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
    inet 127.0.0.1/8 scope host lo
       valid_lft forever preferred_lft forever
    inet6 ::1/128 scope host
       valid_lft forever preferred_lft forever
2: ens33: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc fq_codel state UP group default qlen 1000
    link/ether 00:0c:29:9b:91:81 brd ff:ff:ff:ff:ff:ff
    inet 198.168.1.20/24 brd 198.168.1.255 scope global noprefixroute ens33
       valid_lft forever preferred_lft forever
    inet6 fe80::2de:7698:61b8:808a/64 scope link noprefixroute
       valid_lft forever preferred_lft forever
ms@ubuntu:~$
