You can change Ubuntu IP address with a static IP address or through DHCP. Opting for a static IP allows manual configuration of your network settings on the Linux system, which is ideal for services requiring a consistent address. DHCP, alternatively, lets a router or DHCP server dynamically assign an IP, either reserved or from available addresses.

The best way to change the Ubuntu IP address, according to my research, is using a VPN like ExpressVPN. It secures your IP address changes and facilitates the configuration of DNS servers and default gateways. Its compatibility with Ubuntu and support for all necessary protocols make it an optimal choice for maintaining robust network settings.

The importance of VPNs extends beyond mere IP management. The best VPNs are essential for security and privacy, encrypting your connection and masking your IP address. For Ubuntu users, ExpressVPN offers an easy setup and a wide server network, ensuring control over network settings and safeguarding online activities.

How to Change IP Address in Ubuntu

When it comes to managing your Ubuntu server, changing IP address is a common task that can be achieved through two primary methods. Each method suits different needs and setups, ensuring flexible network management.

How to Change Ubuntu IP Address via Static IP

For Ubuntu IP address change via Static IP follow the below steps:

  1. Locate and Edit the Configuration File: Open the /etc/netplan/50-cloud-init.yaml file, or it may be named /etc/netplan/01-netcfg.yaml in some systems. Use a text editor with administrative privileges for this task.set-ip-address-ubuntu-via-static-ip-in-USA
  2. Update Network Settings: Insert your desired static IP address, DNS server, and gateway into the file.
  3. Apply the Changes: To activate the new settings, use the command: $ sudo netplan apply. If you encounter any issues, you can troubleshoot with: $ sudo netplan –debug apply.
  4. Confirm the IP Address: Verify the new static IP by executing: $ ip a.


How to Change Ubuntu IP Address via DHCP

If your server was previously set with a static IP and you wish to switch to DHCP, the process involves minor edits to the same configuration file:

  1. Edit the Configuration File: Reopen /etc/netplan/50-cloud-init.yaml or /etc/netplan/01-netcfg.yaml. Change the dhcp4 setting under your network interface from false to true.Edit-the-Configuration-File-in-USA
  2. Save and Apply the Changes: After saving the changes, apply them by running: $ sudo netplan apply. Use the debug option if needed.
  3. Verify the DHCP Configuration: Check that the DHCP setting is working by looking at the IP address assignment with: $ ip a.


Ubuntu Linux Change IP using Command Line Config File

By following these steps, you can easily perform an Ubuntu IP change through the GUI, which is often considered a user-friendly method:

Launch the terminal and write the following command:

sudo vi /etc/network/interfaces

Or

sudo gedit /etc/network/interfaces

Go to the eth0 section and set up the IP address as desired.

Now save and close the file and restart the network through this command:

$ sudo /etc/init.d/networking restart 

To confirm the new IP address run this command:

$ ifconfig eth0

$ ifconfig 

Note: To set a static IP address on Ubuntu using the command line, you can utilize the “ifconfig” command.

Following these steps, users can change IP address in Ubuntu according to their network configuration needs. Whether using the GUI for a more visual approach or the Ubuntu change IP address command line method with Netplan for more control, both options provide a reliable way to update network settings.

How to Statically Assign an Ubuntu IP Address

Whenever you are connected to a network, your device immediately gets an IP address from the network. There are two types of IP addresses; static and dynamic. Let’s find out how to assign an Ubuntu static IP address.

  1. First of all, launch Terminal.
  2. Next, run “ip addr show” command to see the network adapter for which you want to change the IP address, and then execute.
  3. Run “ip addr add X.X.X.X/24 dev eth0” command to modify the IP address (you can use any IP address you want to assign).
  4. Once executed, verify the new IP address by running “ip addr show”

How to Permanently Change the IP Address of an Ubuntu VM Using CLI

Changing the IP address of an Ubuntu virtual machine (VM) via the command line interface (CLI) ensures that you can manage your server remotely, even when hardware access is restricted. This guide will provide a detailed approach to permanently changing the IP address on Ubuntu versions 14 through 20, using CLI methods that remain consistent across these versions.

Method 1:

This command shows details about your existing connections, including connection types, DNS configurations, and interfaces.

1. Creating a Permanent IP Configuration with nmcli

The nmcli (Network Manager command-line interface) tool is standard on most Ubuntu installations and allows you to manage networking settings effectively. Here’s how to use nmcli to change your IP address permanently:

  1. Check Existing Network Settings: Begin by reviewing the current settings to avoid conflicts and to ensure correct information is used in your new configuration.

nmcli

2. Create a New Connection: Decide on the properties for your new network connection. Here’s an example command to create a new connection with a static IP:

sudo nmcli connection add connection.id “YOUR_CONNECTION_NAME” \ connection.interface-name “enp0s31f6” \ type ethernet \ ip4 172.18.1.30/24 gw4 172.18.1.1 \ ipv4.dns “8.8.8.8” \ ipv4.method manual

Replace "YOUR_CONNECTION_NAME" with a name of your choice, adjust "enp0s31f6" to your network interface name, and set the ip4, gw4 (gateway), and ipv4.dns fields as per your network requirements.

3. Activate the Connection:
Activate your newly created connection to start using it immediately:

sudo nmcli connection up YOUR_CONNECTION_NAME

4. Verify the Changes:
Check if the settings are applied correctly:

nmcli

5. Restart the Networking Service:
To ensure all configurations are loaded and will persist after a reboot, restart the networking service:

sudo systemctl restart networking.service

Method 2:

Ubuntu 17.10 and later versions typically use Netplan for network configuration, which is a YAML-based configuration system that makes setting up network interfaces straightforward. This method is especially useful if you’re running Ubuntu 18.04 or newer.

Step 1: Identify Your Configuration File

Netplan’s configuration files are typically located in /etc/netplan/. You’ll find one or more YAML files there. To view the content and identify the correct file to edit, use:

ls /etc/netplan/
cat /etc/netplan/your-config-file.yaml

Replace your-config-file.yaml with the actual file name.

2. Edit the Configuration File

  1. Open the Configuration File: Using a text editor such as nano, open the configuration file. sudo nano /etc/netplan/your-config-file.yaml
  2. Modify or Add IP Settings: Here’s an example of what the network configuration might look like for setting a static IP: network: version: 2 ethernets: your_interface_name: dhcp4: no addresses: 172.18.1.30/24 gateway4: 172.18.1.1 nameservers: addresses: 8.8.8.8 “Replace your_interface_name with your actual interface name. Adjust the IP address, gateway, and DNS as needed.”
  3. Apply Changes: After editing the file, apply the changes with: sudo netplan apply.
