How to show IP address on Lubuntu

Alright, this is a beginner's topic, in this article i will teach you how to show IP address on lubuntu from the terminal.

It's very simple, open the terminal (CTRL + ALT + T), and then type the following command :

ifconfig

That's it, that command will show you all network interface on your computer and show the IP address as well.

kernelpanic@lubuntulaptop:~$ ifconfig
eth0      Link encap:Ethernet  HWaddr 00:1e:ec:d3:a8:36 
          UP BROADCAST MULTICAST  MTU:1500  Metric:1
          RX packets:0 errors:0 dropped:0 overruns:0 frame:0
          TX packets:0 errors:0 dropped:0 overruns:0 carrier:1
          collisions:0 txqueuelen:1000
          RX bytes:0 (0.0 B)  TX bytes:0 (0.0 B)

lo        Link encap:Local Loopback 
          inet addr:127.0.0.1  Mask:255.0.0.0
          inet6 addr: ::1/128 Scope:Host
          UP LOOPBACK RUNNING  MTU:65536  Metric:1
          RX packets:3523 errors:0 dropped:0 overruns:0 frame:0
          TX packets:3523 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:0
          RX bytes:335580 (335.5 KB)  TX bytes:335580 (335.5 KB)

wlan0     Link encap:Ethernet  HWaddr 00:21:5d:5f:06:2c 
          inet addr:192.168.43.236  Bcast:192.168.43.255  Mask:255.255.255.0
          inet6 addr: fe80::221:5dff:fe5f:62c/64 Scope:Link
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:120301 errors:0 dropped:0 overruns:0 frame:0
          TX packets:74820 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000
          RX bytes:136331386 (136.3 MB)  TX bytes:11359891 (11.3 MB)

As you can see ifconfig command gives me the eth0 which is my cable network (LAN), lo which is local loopback (localhost), wlan0 which is my wireless network.

You can also shows network interface in individual, the format is ifconfig [interface], for example:

• ifconfig eth0
• ifconfig eth1
• ifconfig lo
• ifconfig wlan0
• ifconfig wlan3

The ifconfig is capable more than just displaying IP address and MAC address, but also it can be use to change IP address, netmask, gateway, etc.

But that would be on another article, for now all you newbie needs to know is how to display IP address using ifconfig.

You can also use iwconfig, which is dedicated command for displaying wireless network interface, go ahead try tying iwconfig on your terminal.

kernelpanic@lubuntulaptop:~$ iwconfig
wlan0     IEEE 802.11abgn  ESSID:"LG-D686_4850" 
          Mode:Managed  Frequency:2.412 GHz  Access Point: BE:F5:AC:D2:88:06  
          Bit Rate=57.8 Mb/s   Tx-Power=15 dBm  
          Retry  long limit:7   RTS thr:off   Fragment thr:off
          Power Management:off
          Link Quality=70/70  Signal level=-39 dBm 
          Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0
          Tx excessive retries:0  Invalid misc:21   Missed beacon:0

lo        no wireless extensions.

eth0      no wireless extensions.
