ip addr is another command to check ip in Linux besides ifconfig. You can first take a look at the output of this command:

[root@localhost ~]# ip addr
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN 
    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: eno16777736: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP qlen 1000
    link/ether 00:0c:29:e7:d7:08 brd ff:ff:ff:ff:ff:ff
    inet 192.168.3.9/24 brd 192.168.3.255 scope global eno16777736
       valid_lft forever preferred_lft forever
    inet6 fe80::20c:29ff:fee7:d708/64 scope link 
       valid_lft forever preferred_lft forever
Copy after login

The command result on my machine displays two parts, lo and eth0. If there are multiple network cards, each network card will display one part.

lo: The full name is loopback, which is the loopback address. It is often assigned to the 127.0.0.1 address and is used for local communication. It returns directly after kernel processing and will not appear on any network.

eth0: Network card name. If there are multiple network cards, there will be multiple eth or other names.
