Set a static IP Address on Raspberry Pi OS Buster

This page details how to set up a static network IP address on the Ethernet connection on the Raspberry Pi OS Buster image from https://www.raspberrypi.org/software/operating-systems/.

For this demo, we will give the Raspberry Pi a static IP address of 10.0.0.220 and a subnet of 24.  The router/gateway address will be set at 10.0.0.1, and the DNS server will also be set as 10.0.0.1

You can find the default gateway for your network with the following command.

netstat -nr

Step 1: Download the latest Raspberry Pi OS image and burn it to your SD Card following the instructions on http://elinux.org/RPi_Easy_SD_Card_Setup.

Step 2: Connect your network cable, boot the Raspberry Pi, and log in via the GUI or terminal.

Step 3: Now we need to edit /etc/dhcpcd.conf

sudo nano /etc/dhcpcd.conf

Step 4:  Add the following at the end of the file and save your changes. Change the IP address, routers and domain name server to match your network.

interface eth0
static ip_address=10.0.0.220/24
static routers=10.0.0.1
static domain_name_servers=10.0.0.1

Step 5: Reboot to apply the changes:

sudo reboot

Your Raspberry Pi will restart and be accessible on the new IP address
