Setting a Static IP on Ubuntu

Identify your network interface name

ip addr

Look for the active interface, typically named eth0 or ens33.

Edit the netplan configuration file

sudo nano /etc/netplan/01-netcfg.yaml

Example configuration

network:
  version: 2
  renderer: networkd
  ethernets:
    eth0:
        addresses:
            - 10.10.10.2/24
        routes:
            - to: default
            via: 10.10.10.1
        nameservers:
            search: [mydomain, otherdomain]
            addresses: [10.10.10.1, 1.1.1.1]

Apply the changes

sudo netplan apply
