This guide assumes you have sudo access on your Raspberry Pi and are comfortable using the terminal.

​
Open a Terminal Window on the Raspberry Pi

If you’re connected directly to your Raspberry Pi with a monitor and keyboard, you can open the terminal by clicking on the terminal icon or pressing Ctrl + Alt + T. If you’re connected via SSH, you are already in a terminal session.

​
Determine Network Interface and Current IP

1

List Network Interfaces

In the terminal, run the following command to list your network interfaces:
ip addr
2

Identify Your Interface

Look for the interface you are using (e.g., eth0 for wired connection or wlan0 for wireless). Note down the interface name.
3

Find Current IP Address

Under the interface, look for the inet line to find your current IP address. Note down the IP address, subnet mask, router (gateway), and DNS server.

​
Edit the dhcpcd Configuration File

1

Open the Configuration File

Use a text editor like nano to edit the dhcpcd.conf file:
sudo nano /etc/dhcpcd.conf
2

Add Static IP Configuration

Scroll to the end of the file and add the following lines, replacing the placeholders with your actual network details:
interface <your_interface_name>
static ip_address=<desired_static_ip_address>/<subnet_mask>
static routers=<your_router_ip>
BlueOS Example:
interface eth0
static ip_address=192.168.2.2/24
static routers=192.168.2.1
3

Save and Exit

Press Ctrl + X to exit, then Y to save changes, and Enter to confirm the file name.

​
Restart the Raspberry Pi

Restart your Raspberry Pi to apply the changes: 
sudo reboot -h now

​
Verify the Static IP Configuration

After rebooting, open the terminal on the Raspberry Pi and run: 
ip addr
Confirm that your interface now has the static IP address you configured.
If you are unable to connect to your Raspberry Pi after setting a static IP, ensure that the IP address is within your network’s range and does not conflict with other devices.
