Netplan is an utility developed by Canonical, the company behind Ubuntu. It provides a network configuration abstraction over the currently supported two “backend” system, (or “renderer” in Netplan terminology): networkd and NetworkManager. Using Netplan, both physical and virtual network interfaces are configured via yaml files which are translated to configurations compatible with the selected backend.

On Ubuntu 20.04 Netplan replaces the traditional method of configuring network interfaces using the /etc/network/interfaces file; it aims to make things easier and more centralized (the old way of configuring interfaces can still be used: check our article about How to switch back networking to /etc/network/interfaces on Ubuntu 20.04 Focal Fossa Linux). In this article we will learn the basic principles behind the utility, and, just as an example, how we can use it to configure a static IPv4 address for a network interface.

In this tutorial you will learn:

• The basic structure of yaml configuration files used by Netplan
• How to create a simple rule to assign a static IP to a network interface
• How to apply configurations using generate, try and apply subcommands

Downloading Ubuntu ISO images with a torrent client is one of the most efficient ways to obtain the installation media. Torrenting allows you download the file from multiple sources simultaneously, which means you'll wind up with a very speedy download because the entirety of your network's download bandwidth can remain saturated. It's a very reliable method for downloading large files.

It also takes some strain off of official Ubuntu mirrors, so you're actually helping them out a little by getting an ISO image from the torrent swarm. If you want to continue helping after the download completes, you can choose to leave the Ubuntu torrent in your torrent client and let it "seed" (torrenting jargon for upload) to other prospective downloaders.
