Ubuntu 26.04 continues using Netplan as the default network configuration system, just like earlier Ubuntu releases, but instead of editing older configuration files manually, you now manage network settings using simple YAML files stored under /etc/netplan/.
For desktop users, Netplan usually works quietly in the background, but on VPS servers, home labs, or remote Ubuntu systems, knowing how to configure static IP addresses, DNS servers, and multiple interfaces becomes very important, because a small YAML mistake can even disconnect your server if you’re working remotely over SSH.
In this article, you’ll learn how to configure Netplan on Ubuntu 26.04, including DHCP, static IP addresses, DNS settings, and common troubleshooting tips that can save you during late-night server fixes.
