IP Address: What Is It?

How about we quickly learn about the IP address before we get a little more technical?

The full definition of what IP means is Internet Protocol Address. Every device you use will get a different set of numbers when connected to any network. When using a network for your device, numbers get assigned to you, and the numbers are how devices on the network or on the internet use to reach your device.

There are a few different types of IP Addresses:

Private IP Address
Public IP Address

Private IP Address is used on local and internal networks. Public IP Addresses are assigned by your Internet Service Provider and are used for communication over the internet.

Use for IP Address Knowledge in Linux

There are tons of reasons to know your IP Address such as:

Troubleshooting network issues
Setting up servers or SSH connections
Configuring firewalls
Managing cloud or VPS systems
Debugging connectivity

Creating problems for yourself by not knowing how to find your IP Address in Linux is not the long game, so don’t go that route.

Method 1: Check IP Address with the Command (This is the Expected Method)

The command is the preferred command which you can use to check your IP address in Linux.

Command:

ip addr show

The server displays a list of network interfaces and IP Addresses.

Example Output:

2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP>
    inet 192.168.1.10/24

Explanation:

192.168.1.10 is your IP Address

For the short version, you can use:

ip a

Method 2: the Command hostname -I

Another simple and fast way to check your IP Address is:

hostname -I

Example Output:

192.168.1.10

This command prints your system IP Address.

Method 3: the Command Ifconfig

This is another way you can find your IP Address and is preferred by some users.

Command:

ifconfig

If this is not installed:

sudo apt install net-tools

Expected Output:

inet 192.168.1.10

Method 4: Public IP Address Check

Use a website or terminal command to check your public IP address.

curl ifconfig.me

curl ipinfo.io/ip

These commands will show your public IP, which is different from your private IP.

Method 5: Using nmcli Command

If you are using NetworkManager:

nmcli -p device show

This is another useful method for checking IP address in Linux.

Understanding Output of IP Commands

When using commands like ip addr, you may see:

lo – Loopback interface (127.0.0.1)
eth0 / ens33 – Wired connection
wlan0 – Wireless connection

You should focus on:

inet xxx.xxx.xxx.xxx

This is your actual IP address.

How to Check IP for Specific Interface

If your system has multiple interfaces:

ip addr show eth0

ip addr show wlan0

This is useful for servers and advanced networking.

Linux Distribution Notes

Ubuntu

Best options:

ip a

hostname -I

GUI Method:

Go to Settings
Click Network
View IP Address

CentOS / Red Hat

ip addr

nmcli

Kali Linux

ip a

ifconfig

Common Mistakes

Beginners usually make the following mistakes:

Misunderstanding public vs private IP
Not installing required tools
Focusing on loopback address (127.0.0.1)
Not identifying the correct interface

Tips for Beginners

Use ip a (modern command)
Use hostname -I (quick method)
Use curl for public IP
Learn interface differences

Real-World Use Cases

Linux IP knowledge is useful for:

Website creation
SSH connections
Server management
Cloud services (AWS, Azure, etc.)
Networking labs

Summary

Knowing how to find your IP address in Linux can be simple:

ip addr → Best method
hostname -I → Quick method
ifconfig → Older but useful
curl → Public IP

Final Thought

Linux learning involves understanding how to check your IP address, which helps in mastering networking concepts.

Both beginners and experts can benefit from practicing regularly and improving their skills over time.
