How to Configure Static IP Address on Ubuntu 26.04

To configure a static IP address on Ubuntu 26.04, write a Netplan file and apply it. Use the NIC from step 1 and the file from step 2. Pick a static IP and a gateway (example 192.168.1.1).

Step 1 : Note the interface name (example: ens3).

ip -br addr

Step 2 : Use the Netplan file on this machine (ISO: 00-installer-config.yaml; cloud: 50-cloud-init.yaml).

ls /etc/netplan/

Step 3 : Back up the file from step 2.

sudo cp /etc/netplan/00-installer-config.yaml /etc/netplan/00-installer-config.yaml.bak

Step 4 : NIC from step 1. File from step 2. Set your static IP (example 192.168.1.50) and gateway (example 192.168.1.1).

sudo tee /etc/netplan/00-installer-config.yaml <<'EOF'
network:
  version: 2
  ethernets:
    ens3:
      dhcp4: false
      addresses:
        - 192.168.1.50/24
      nameservers:
        addresses: [8.8.8.8, 1.1.1.1]
      routes:
        - to: default
          via: 192.168.1.1
EOF

Step 5 : Apply.

sudo netplan apply

Step 6 : Test.

ping -c 4 google.com
