[brent]

Configure static IP address using Netplan

Netplan network configuration had been first introduced to Ubuntu 18.04 LTS Bionic Beaver. It is available to all new Ubuntu 18.04 installations. 

Ubuntu Server

To configure a static IP address on your Ubuntu 20.04 server you need to modify a relevant netplan network configuration file within /etc/netplan/ directory. 

This static configuration has been depreciated

network:
  ethernets:
    enp0s3:
      addresses: [192.168.1.3/24]
      gateway4: 192.168.1.1
      nameservers:
        addresses: [4.2.2.2, 8.8.8.8]
  version: 2

This is the new static configuration.

network:
  ethernets:
    enp0s3:
      addresses: [192.168.1.3/24]
      routes:
        - to: default
          via: 192.168.1.99
      nameservers:
        addresses: [4.2.2.2, 8.8.8.8]
  version: 2
