Set Static IP with Pi-hole DNS on Raspberry Pi

These instructions guide you through setting a static IP address (192.168.1.2) on a Raspberry Pi running Bookworm OS using nmtui, with the Pi configured to use itself as the DNS server for Pi-hole.

Prerequisites

• Raspberry Pi OS Bookworm is installed.
• You have terminal access (via SSH or directly).
• NetworkManager is installed (default in Bookworm).
• Pi-hole is installed and will use 192.168.1.2 as its address.
• You router will use 192.168.1.1 as its address.

Steps to Configure

1. Open the Terminal

   Log in to your Raspberry Pi and open a terminal.

2. Launch nmtui

   Run this command:

   sudo nmtui

3. Navigate to “Edit a Connection”

   Use arrow keys to select “Edit a connection” and press Enter.

4. Select Your Network

   Highlight your connection (e.g., Wired connection 1 for Ethernet or your Wi-Fi name) and press Enter.

5. Configure IPv4 Settings

   Scroll to “IPv4 CONFIGURATION”, change from Automatic to Manual, and press Enter.

6. Set Static IP and DNS
   • Addresses: Enter 192.168.1.2/24 (subnet mask 255.255.255.0).
   • Gateway: Enter your router’s IP (e.g., 192.168.1.1).
   • DNS servers: Enter 192.168.1.2 (the Pi’s own IP for Pi-hole).
7. Save the Configuration

   Scroll to “OK” and press Enter, then Esc to return to the main menu.

8. Exit nmtui

   Select “Quit” and press Enter.

9. Restart the Network

   Apply changes with:

   sudo systemctl restart NetworkManager

   Or reboot:

   sudo reboot

10. Verify the Static IP

    Check with:

    ip addr

    Ensure 192.168.1.2 is assigned to your interface (e.g., eth0 or wlan0).

Example Configuration

• Static IP: 192.168.1.2/24
• Gateway: 192.168.1.1
• DNS: 192.168.1.2 (Pi-hole)
