How to config static IP address in Ubuntu 18.04 server with Netplan

Ubuntu 18.04 uses now Netplan to configure the network interfaces, so the configuration must be done in the file /etc/netplan/50-cloud-init.yaml

sudo vi /etc/netplan/50-cloud-init.yaml

DHCP address:

network:
  version: 2
  renderer: networkd
  ethernets:
    enp3s0:
      dhcp4: true

Static address:

network:
  version: 2
  renderer: networkd
  ethernets:
    enp3s0:
      addresses:
        - 10.10.10.2/24
      gateway4: 10.10.10.1
      nameservers:
          addresses: [10.10.10.1, 1.1.1.1]

NOTE:

  • It’s using yaml format, you should use space rather than tab.
