Summary
An IP address is the fundamental pointer that tells other devices where to find your Raspberry Pi on a network.
Without it, trying to communicate with your Pi is like trying to send a letter without an address.
It simply won’t get there. So, learning how to find this crucial piece of information is one of the first and most important skills you'll master.
Let's explore why this address is so vital and the various ways you can find it.
Why Do You Need to Know Your Raspberry Pi IP Address?
Before diving into the "how," it's useful to understand the "why." Your Raspberry Pi is more than just a tiny desktop computer; it's a gateway to countless projects, from home automation hubs to personal web servers.
Most of these applications involve connecting to the Pi remotely, without a dedicated monitor, keyboard, or mouse. This is where knowing its IP address becomes essential.
- Remote Access and Headless Operation: The most common reason to need the IP address is for "headless" operation. This allows you to control your Raspberry Pi from another computer using services like SSH (Secure Shell) for command-line access or VNC (Virtual Network Computing) for a full graphical desktop experience. You need the Raspberry Pi IP Address to tell your main computer where to connect.
- Hosting Services: If you're using your Pi to host a website, a media server like Plex, or a network-attached storage (NAS) system, you and other users on your network need its IP address to access those services. For services you want to make available over the internet, you often need to set up port forwarding on your router, a process that is simplified by having a stable, known IP address.
- Network Management and Troubleshooting: When you have multiple devices on your network, knowing each one's IP address helps with organization and troubleshooting. If your Pi can't connect to the internet or other devices, one of the first diagnostic steps is to check its network configuration, which starts with the IP address.
- Development and IoT Projects: For Internet of Things (IoT) projects, your Raspberry Pi often acts as a central controller that communicates with various sensors and devices. A consistent Raspberry Pi IP Address ensures that these components can reliably send data to and receive commands from the Pi.

4 Methods to Check Raspberry Pi IP Address
Finding your Pi’s digital address can be done in several ways, depending on your setup. You might have it connected to a monitor, or it might be running headless somewhere in your home. Here are four reliable methods to find it.
1. Using the Raspberry Pi Command Line
If you have a monitor and keyboard connected to your Pi, the command line (or terminal) is the most direct and powerful way to get network information.
Open the terminal application from the desktop or boot into the command-line interface. Here are a few commands that will help you get the Raspberry Pi IP address.
The most modern and recommended command is ip addr show. It provides a detailed breakdown of all network interfaces.
ip addr show
You will see a list of interfaces. eth0 typically represents the wired Ethernet connection, and wlan0 is for Wi-Fi. Look for the line that starts with inet followed by a set of numbers; this is your local IP address.
You might see an inet6 address as well, which is the newer IPv6 format. For most home networks, you'll be interested in the inet (IPv4) address.
Another very common raspberry pi IP address command is hostname -I. This one is much more direct.
hostname -I
This command strips away all the extra information and prints only the IP address (or addresses, if connected to multiple networks) directly to the terminal.
It's quick, clean, and easy to read, making it a favorite for many users. Using this command is a straightforward way to find the IP address of the Raspberry Pi.
An older, but still functional, command is ifconfig. While it's being phased out in favor of the ip command on many Linux systems, it's still available on Raspberry Pi OS.
ifconfig
Similar to ip addr show, ifconfig will list all network interfaces. You'll look for eth0 or wlan0 and find the inet field to see the Raspberry Pi IP Address.
2. Checking the IP Address via Router Settings
What if your Pi is running headless and you've never connected to it before? One of the most reliable methods is to look at your network's master traffic controller: your router. This method requires you to log into your router's administrative interface.
- Find Your Router's IP Address: First, you need to access your router. On a Windows computer, open the Command Prompt and type ipconfig. Look for the "Default Gateway." On a Mac, go to System Settings > Network, select your active connection, and find the "Router" address. This address is usually something like 192.168.1.1 or 192.168.0.1.
- Log In to Your Router: Open a web browser on any computer connected to your network and enter the router's IP address into the address bar. You'll be prompted for a username and password. These are often printed on a sticker on the router itself or can be found online with a quick search for your router's model.
- Find the Connected Devices List: Once logged in, look for a section named "Connected Devices," "Device List," "DHCP Clients," or something similar. This page will show every device currently connected to your network.
- Identify Your Raspberry Pi: Scan the list for your Pi. By default, its hostname is "raspberrypi". You should see this name next to an IP address. This is the IP address of your raspberry pi. Write it down, and you can now use it to connect remotely. This method is excellent because it doesn't require any software installation and works for any device on your network.
3. Finding Raspberry Pi IP Address on Windows/Mac/Linux
You can also find your Pi from another computer on the same network using various network scanning commands and tools.
One of the simplest techniques is to use the ping command with the Pi's default hostname.
Most modern networks support multicast DNS (mDNS), which allows devices to be discovered by their hostname. Open a Command Prompt (Windows) or Terminal (Mac/Linux) and type:
ping raspberrypi.local
If the network resolves the name, it will start sending packets to the Pi, and the output will show the Raspberry Pi IP Address in parentheses.
Note that this may not work on all Windows systems without installing an mDNS service like Apple's Bonjour, but it typically works out of the box on macOS and most Linux distributions.
For a more thorough scan, you can use a network scanning tool like nmap. If you don't have it, you can install it on most operating systems. Once installed, you first need to find out your network's subnet.
Run ipconfig (Windows) or ifconfig/ip addr (Mac/Linux) on your computer to find its IP address. If your computer's IP is, for example, 192.168.1.5, your subnet is likely 192.168.1.0/24.
You can then run nmap with the -sn flag to scan the entire subnet:
nmap -sn 192.168.1.0/24
This command will ping every possible address in the range and report back which ones are active, along with their hostnames if available.
Look for the entry for "raspberrypi" to find the IP address of the Raspberry Pi Board.
If you prefer a graphical tool, applications like "Advanced IP Scanner" for Windows, or "Fing" for mobile devices and desktops, offer a user-friendly way to scan your network and see everything that's connected, including the Raspberry Pi's IP address.
4. Using Raspberry Pi OS Desktop Interface
If you're running Raspberry Pi OS with its full graphical desktop, there's an even simpler way that doesn't require typing any commands.
The desktop environment is designed to be user-friendly, and that includes providing easy access to network information.
On the top-right corner of the screen, in the taskbar, you will see a network icon. If you are connected via Wi-Fi, it will look like a typical Wi-Fi symbol.
If you are using a wired connection, it will look like two computer monitors.
Simply hover your mouse cursor over this network icon. After a moment, a tooltip will appear displaying your network status, including the connection method (wired or wireless), the network name (SSID) for Wi-Fi, and, most importantly, the IP address assigned to that interface.
It's a quick, visual way to check your connectivity at a glance, perfect for beginners or when you just need a fast confirmation.
Conclusion
Just like a physical address lets you navigate the real world, an IP address is your guide to the digital address of the devices in the network.
Finding your Raspberry Pi's IP address is a fundamental skill that transforms it from an isolated gadget into a networked powerhouse.
Whether you're delving into the command line, exploring your router's settings, scanning your network, or using the graphical desktop, there is a method that fits your setup and skill level.
