Wonder what’s your IP address? Here are several ways to check IP addresses in Ubuntu and other Linux distributions.

Want to know your Linux system's IP address? You can use the ip command with the option a like this:

ip a

The output is extensive and it shows all the internet interfaces available, including loopback. Identifying the IP address could seem challenging if you are new to it.

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 scope host lo
       valid_lft forever preferred_lft forever
    inet6 ::1/128 scope host 
       valid_lft forever preferred_lft forever
2: enx747827c86d70: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc pfifo_fast state DOWN group default qlen 1000
    link/ether 74:78:27:c8:6d:70 brd ff:ff:ff:ff:ff:ff
3: wlp0s20f3: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP group default qlen 1000
    link/ether dc:41:a9:fb:7a:c0 brd ff:ff:ff:ff:ff:ff
    inet brd scope global dynamic noprefixroute wlp0s20f3
       valid_lft 82827sec preferred_lft 82827sec
    inet6 fe80::e1d:d71b:c507:5cc8/64 scope link noprefixroute 
       valid_lft forever preferred_lft forever

It really is not, actually.

And there are other ways to find the IP address. I'll discuss all this in detail. But first, let's brush up the basics.

What is an IP Address?

An Internet Protocol address (commonly referred to as the IP address) is a numerical label assigned to each device connected to a computer network (using the Internet Protocol). An IP address serves both the purpose of identification and localisation of a machine.

The IP address is unique within the network, allowing communication between all connected devices.

You should also know that there are two types of IP addresses: public and private. The public IP address is used to communicate over the Internet, the same way your physical address is used for postal mail. However, in the context of a local network (such as a home where a router is used), each device is assigned a unique private IP address within this sub-network. This is used inside this local network without directly exposing the public IP (which the router uses to communicate with the Internet).

Another distinction can be made between IPv4 and IPv6 protocols. IPv4 is the classic IP format, consisting of a basic 4-part structure, with four bytes separated by dots (e.g., However, with the growing number of devices, IPv4 will soon be unable to offer enough addresses. This is why IPv6 was invented, a format that uses 128-bit addresses (compared to the 32-bit IPv4).

Checking your IP Address in Ubuntu [Terminal Method]

The fastest and simplest way to check your IP address is by using the ip command. You can use this command in the following fashion:

ip a

Actually, it’s short for this:

ip addr show

Both commands show the same output. They will show you both IPv4 and IPv6 addresses:

Display IP Address in Ubuntu Linux
Display IP Address in Ubuntu Linux

You should identify the correct interface and then look beside inet for IPv4 and inet6 for IPv6.

For example, inet means the IPv4 address is

Just get the IP address

The hostname command might not be available in all Linux distros.

If you prefer to get minimal details, you can also use the hostname command:

hostname -I

It will just give the IP address of the system. Nothing else.

Hostname only shows IP address
Hostname only shows IP address

There are other ways to check IP addresses in Linux but these two commands are more than enough to serve the purpose.

Long-time users might be tempted to use ifconfig (part of net-tools), but that command is deprecated. Some newer Linux distributions don’t include this package anymore and if you try running it, you’ll see the ifconfig command not found error.

Checking IP address in Ubuntu [GUI Method]

If you are not comfortable with the command line, you can also check the IP address graphically.

Open up the Ubuntu Applications Menu (Show Applications in the bottom-left corner of the screen) and search for Settings and click on the icon:

Open system settings from Ubuntu Activities Overview
Open Settings in Ubuntu

This should open up the Settings Menu. Go to Network:

Open settings for the currently connected network from the gear icon adjacent to the name of that particular connection
Network Settings in Ubuntu

Pressing on the gear icon next to your connection should open up a window with more settings and information about your link to the network, including your IP address:

IP Address details in Ubuntu System Settings
IP Address GUI Ubuntu

You can see the IP address of your router as well in the above screenshot. It’s displayed with “Default Route”.

Bonus Tip: Checking your public IP address (for desktop computers)

First of all, to check your public IP address (used for communicating with servers etc.) you can use the curl command. Open up a terminal and enter the following command:


This should simply return your IP address with no additional bulk information. I would recommend being careful when sharing this address since it is equivalent to giving out your personal address.

If curl isn’t installed on your system, simply use sudo apt install curl -y to install curl on Ubuntu-based Linux distributions.

Another simple way you can see your public IP address is by searching for the IP address on Google.


Here's a summary of the commands you learned:

Description Command
Show both IPv4 and IPv6 addresses with ip command ip a or ip addr show
Print only IP address using hostname command hostname -I
To check your public IP address (Need curl installed) curl
Display IP Address with Network Manager tool nmcli -p device show
Use the ifconfig command to display the IP address (Need net-tools installed ) ifconfig -a

Now that you know your system's IP address, how about getting the gateway IP?

In this article, I went through the different ways you can find your IP address in Ubuntu Linux, as well as gave you a basic overview of what IP addresses are used for and why they are so important to us.

I also discussed IPv4 and IPv6 briefly. By the way, have you ever wondered why there is no IPv5?

If you have spent any amount of time in the world of the internet, you should have heard about the IPv4 and IPv6 protocols that our computers use every day. One question that you might be asking is: Why there is no IPv5? Why IPv6 came after IPv4 and not
