Netplan Static IP

/etc/netplan/50-cloudinit.yaml (or other, higher-numbered file):

network:
  version: 2
  ethernets:
    ens192:
      dhcp4:false
      addresses: 
        - 192.168.1.19/24
      routes: 
        - to: default
          via: 192.168.1.1
      nameservers:
        addresses: [192.168.1.5]
        search: [example.com]
      match:
        macaddress: 00:11:22:33:44:55
      set-name: ens192

tip Vim Magic You can use vim’s :r[ead] command to read in the mac address without having to copy/paste, bounce between terminals, or memorize it:

<Esc>:r /sys/class/net/ens192/address

sudo netplan apply
