In this short article, we would like to show how under Linux find the IP address of current machine using the command line.

Quick solution (run in terminal):

ip addr

More detailed description

Modern Linux should have installed ip program - this article shows how to use it.

Hint: using an external tool is not a good solution as our computer may be on a local network - for example, we don't have our own public IP address or we are connected to a local WiFi or router.

Use the following command:

ip addr

Output:

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: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP group default qlen 1000
    link/ether 00:15:5d:0d:77:06 brd ff:ff:ff:ff:ff:ff
    inet 192.168.153.186/20 brd 192.168.159.255 scope global dynamic noprefixroute eth0
       valid_lft 73676sec preferred_lft 73676sec
    inet6 fe80::4810:db19:e572:7a6a/64 scope link noprefixroute 
       valid_lft forever preferred_lft forever

Explanation:

eth0 network interface (ethernet connection) has 192.168.153.186 IP address.
