Setting up a Static IP on Ubuntu configuration is essential for servers, remote access systems, media servers, and devices that require a permanent network address. By default, Ubuntu receives IP addresses dynamically from a DHCP server, but many advanced networking tasks work better with a fixed IP.
Whether you manage an Ubuntu server or desktop machine, configuring a static IP improves stability and simplifies remote connectivity.
Dynamic IP addresses can change after router reboots or network reconnects. This may interrupt SSH access, port forwarding, DNS records, or locally hosted services.
A static IP solves these issues by assigning a permanent address to your Ubuntu system. It is especially useful for:
Ubuntu uses Netplan for network management on modern releases, making static IP configuration more consistent across systems.
Before assigning a static address, identify your network interface name using:
ip link
Ubuntu systems often use interface names such as ens3, enp0s3, or eth0.
Next, locate the Netplan configuration file:
ls /etc/netplan/
Open the YAML file with a text editor:
sudo nano /etc/netplan/01-netcfg.yaml
A basic static IP configuration may look like this:
network: version: 2 renderer: networkd ethernets: ens3: dhcp4: false addresses: - 192.168.1.50/24 routes: - to: default via: 192.168.1.1 nameservers: addresses: - 8.8.8.8 - 1.1.1.1
Make sure the indentation remains correct because YAML formatting is strict.
Before applying changes permanently, test the configuration safely:
sudo netplan try
If everything works correctly, apply the configuration:
sudo netplan apply
Desktop users can configure networking without editing files manually.
Open:
Settings → Network
Select the active network interface and open IPv4 settings. Switch the method from Automatic (DHCP) to Manual.
Enter:
After saving the settings, reconnect the network adapter to apply the new configuration.
Incorrect interface names are one of the most common issues. Always verify them with the ip link command.
Another frequent problem involves YAML indentation errors in Netplan files. Even a single misplaced space can prevent the network configuration from loading correctly.
If DNS stops working after the change, double-check the nameserver section and confirm the DNS addresses are properly formatted.
Configuring a Static IP on Ubuntu setup helps create a more stable and predictable networking environment for servers and desktop systems alike. Netplan offers a powerful way to manage networking from the command line, while Ubuntu Desktop provides an easy graphical method for less technical users.
For remote systems accessed through SSH, always test changes with netplan try before applying them permanently.
