Set a Static IP Address on Ubuntu
This guide explains how to configure a static IP address on Ubuntu using the netplan configuration system. Setting a static IP is useful for servers or devices that need a consistent network address.
1. Locate the Network Configuration File
1
2
cd /etc/netplan/
ls
This will list the available .yaml files. Typically, there is only one file, such as 01-netcfg.yaml or a similarly named file.
2. Edit the Configuration File
Open the configuration file for editing. Replace <netcfg> with the actual filename you found in the previous step:
1
sudo nano /etc/netplan/<netcfg>.yaml
Modify the file to include the static IP configuration. Below is an example configuration:
1

network:
version: 2
renderer: networkd
ethernets:
enp5s0: # Replace with your network interface name
dhcp4: no
dhcp6: no
addresses: [157.80.92.139/24] # Replace with your desired static IP and subnet mask
routes:
- to: default
via: 157.80.92.11 # Replace with your router's IP address
nameservers:
addresses: [8.8.8.8, 8.8.4.4] # Replace with your preferred DNS servers
Note: Ensure that the static IP address is within the same subnet as your router and does not conflict with other devices on the network.
3. Apply the Configuration
1
sudo netplan apply
This will activate the static IP settings.
4. Verify the Configuration
To confirm that the static IP address has been applied, use the following command:
1
ip a
