Using Netplan to set up a Static IP Configuration

Using Netplan to set up a Static IP Configuration

Here's a sample from the new Linux Networking - Basics and Beyond video course. In this excerpt, I show how to configure static IP addresses (and other networking) on an Ubuntu Server within the Netplan YAML configuration file. Enjoy!

Check out the video and lab document below:

Lab 09 ⚙️ Using Netplan to set up a Static IP Configuration

Netplan is the front-end utility that is used to configure TCP/IP for Ubuntu Servers. The configuration files are written in YAML. In this lab we show how to view and re-configure Netplan.

Analyze the netplan configuration

Open the netplan configuration:

For example: vim /etc/netplan/00-installer-config.yaml

Here's an example of a netplan .yaml file in Ubuntu server:

        - to: default
  version: 2
  renderer: networkd

Take a minute to analyze your configuration.

The network interface name is enp1s0. The IP address of the server is The gateway and DNS server IPs are one and the same:

Note: You can also use square brackets for some of the IP addresses. By doing so, you can easily add IP addresses, by comma-separating them. For example:


Note: You might not see the renderer line item. This allows you to change the base network service that the system uses. For example, if NetworkManager was installed to the Ubuntu Server and we wanted to use it as our primary network service, we could change the setting from networkd to NetworkManager and then Netplan would interface with that instead.

Modify the netplan Configuration

If your configuration shows DHCP, then modify it to a static address, similar to the configuration above, but based on your IP network. Otherwise, change the IP address to something different, for example, from .53 to .153. Then, save and quit out of your text editor.

You can have netplan check your configuration by typing netplan try.

If there are no error messages, proceed by saving the configuration: netplan apply

Then test it with ping

👍 Nicely done
