Setup a Raspberry Pi Static IP Address

-

Introduction

The Raspberry Pi is an incredibly versatile single-board computer beloved by hobbyists and professionals alike. Setting up a static IP address for your Raspberry Pi is crucial when using it as a server, IoT hub, or for any application requiring consistent network access. This guide provides a comprehensive, user-friendly walkthrough to help you establish a static IP address and ensure reliable connectivity.

Why Setup a Static IP Address?

A static IP address offers several benefits, including:

  • Reliable Access: Ensures your Raspberry Pi is always reachable at the same IP.

  • Network Stability: Reduces conflicts in DHCP environments.

  • Ease of Configuration: Simplifies the management of devices connected to your network.

If your Raspberry Pi hosts services like a web server or VPN, a static IP address is essential for uninterrupted functionality.

Prerequisites

Before you begin, ensure you have:

  1. A Raspberry Pi with Raspberry Pi OS installed.

  2. SSH access to your Raspberry Pi (or a connected monitor and keyboard).

  3. Basic knowledge of network concepts (IP addresses, gateways, etc.).

  4. Your network details (current IP, subnet mask, gateway, and DNS server).

In this tutorial, I use the Raspbian operating system. Here's how to setup a Raspberry Pi Static IP Address.

Recommended Equipment

  • Raspberry Pi

  • Micro SD Card

  • Power Supply

  • Ethernet Cord or WiFi dongle (The Pi 3 and 4 has WiFi inbuilt)

Step-by-Step Guide to Setup a Static IP Address

Step 1: Retrieve Network Information

We will first need to retrieve some information about your network. Use the following command:

ip r | grep default

This command will show your default gateway.

Step 2: Retrieve Current DNS Server

Open the resolv.conf configuration file to identify or set the DNS server:

sudo nano /etc/resolv.conf

Set the nameserver to an alternative DNS, such as 8.8.8.8 for Google or 1.1.1.1 for Cloudflare.

Step 3: Modify the Network Configuration

Edit the dhcpcd.conf file to define a static IP address:

sudo nano /etc/dhcpcd.conf

Add the following lines, replacing placeholders with your details:

interface <NETWORK>
static ip_address=<STATIC_IP>/24
static routers=<ROUTER_IP>
static domain_name_servers=<DNS_IP>

  • NETWORK: Your network connection type: eth0 (Ethernet) or wlan0 (wireless).

  • STATIC_IP: The static IP address you want to set for the Raspberry Pi.

  • ROUTER_IP: The gateway IP address for your router on the local network.

  • DNS_IP: The DNS IP address (typically the same as your router’s gateway address).

Save the file by pressing CTRL + X, then Y, followed by ENTER.

Step 4: Restart the Raspberry Pi

Restart your Raspberry Pi to apply the changes:

sudo reboot

Step 5: Verify the Static IP

Test the new static IP address using:

hostname -I

Ensure the IP matches the one you configured.

Advanced Scenarios

Setting Up Multiple Static IPs

To configure multiple static IPs for the same interface, add additional static ip_address entries in dhcpcd.conf:

static ip_address=192.168.1.101/24
static ip_address=192.168.1.102/24

Using Static IP with IPv6

For IPv6, include the following in dhcpcd.conf:

interface eth0
static ip6_address=fd51:42f8:caae:d92e::1/64
static routers=fd51:42f8:caae:d92e::1
static domain_name_servers=fd51:42f8:caae:d92e::1

FAQ

Why is my static IP not working?

  • Check for typos in the dhcpcd.conf file.

  • Ensure the IP is outside the DHCP range of your router.

  • Restart your router and Raspberry Pi.

Can I revert to a dynamic IP?

Yes, by removing or commenting out the static IP configuration in dhcpcd.conf and restarting the network service:

sudo systemctl restart dhcpcd

What happens if two devices share the same static IP?

IP conflicts can disrupt network connectivity. Ensure your chosen IP is unique.

Bash script list all IP addresses connected to Server with Country Information

-
Introduction This script is designed to list all IP addresses connected to your server, retrieve geographical information for each IP using ipinfo.io , and display the results in a clean format. This guide will walk you through the script, explaining each part in detail, and ensuring you understand how to implement and use it effectively. What is Bash? Bash (Bourne Again Shell) is a Unix shell and command language written by Brian Fox for the GNU Project as a free software replacement for the Bourne shell. It has since become the default login shell for most Linux distributions.
