Static IP Configuration - Ubuntu 22.04.2

By default Ubuntu will create a file called 00-installer-config.yaml under /etc/netplan/ you can either create another yaml file but I like to adjust the configuration of the default one since its easier. 

1. Open up the config file in nano or your preferred editor. 

sudo nano -K /etc/netplan/00-installer-config.yaml

2. Use the example configuration pages below to adjust your settings. The difference between the two examples is just formatting, either will work.

Example 1:

network:
  version: 2
  ethernets:
    ens160: #Interface, you can run (ip -a) in the shell to find the exact one you want
      dhcp4: no
      addresses:
        - 10.1.0.20/24 #IP Address with subnet
      routes:  
        - to: default
          via: 10.1.0.1  #Routers IP
      nameservers:
    	search: [in.rem.pub, dmz.rem.pub] #Allows host name lookup without FQDN
        addresses: [10.1.0.50, 10.1.0.51] #DNS Servers, Primary and Secondary

Example 2:

network:
  version: 2
  ethernets:
    ens160: #Interface, you can run (ip -a) in the shell to find the exact one you want
      dhcp4: no
      addresses:
        - 10.1.0.20/24 #IP Address with subnet
      routes:  
        - to: default
          via: 10.1.0.1  #Routers IP
      nameservers:
    	search: #Allows host name lookup without FQDN
          - in.rem.pub
          - dmz.rem.pub 
        addresses: #DNS Servers, Primary and Secondary
          - 10.1.0.50
          - 10.1.0.51

If you are using IPv6, the addresses must be inside quotes.

3. Apply the configuration.

sudo netplan apply
