How to Configure a Static IP Address on Ubuntu 22.04

In this tutorial, we will show you how to configure a static IP address on Ubuntu 22.04. A static IP address is a permanent IP address that is assigned to a device on a network. This is in contrast to a dynamic IP address, which is assigned to a device temporarily by a DHCP server.

There are several reasons why you might want to use a static IP address on your Ubuntu server. For example, if you want to host a website or other service on your server, you will need to have a static IP address so that people can access it from the outside world. Additionally, a static IP address can be helpful if you want to connect to your server remotely using SSH or other remote management tools.

Configuring a static IP address on Ubuntu 22.04 is relatively straightforward. In this tutorial, we will walk you through the steps involved.

Prerequisites:

• You must be logged in to your Ubuntu server as a user with sudo privileges.
• You must have the net-tools package installed. This package is included by default in Ubuntu 22.04.

Instructions:

1. Open the terminal.
2. Type the following command to list the current IP address of your server:

“`
ip addr show
“`

3. The output of this command will show you the current IP address of your server, along with other information such as the network interface and the subnet mask.

4. To configure a static IP address, you need to edit the `/etc/netplan/01-netcfg.yaml` file. This file contains the network configuration for your server.

5. Open the `/etc/netplan/01-netcfg.yaml` file in a text editor.

6. Find the `network` section and add the following lines:

“`
network:
version: 2
renderer: networkd
ethernets:
enp0s3:
dhcp4: no
addresses: [192.168.1.100/24]
gateway4: 192.168.1.1
netmask: 255.255.255.0
“`

7. Save and close the `/etc/netplan/01-netcfg.yaml` file.

8. Run the following command to apply the new network configuration:

“`
netplan apply
“`

9. Verify that the static IP address has been configured correctly by running the following command:

“`

What is a static IP address?

A static IP address is a permanent IP address that is assigned to a device on a network. This is in contrast to a dynamic IP address, which is assigned to a device temporarily by a DHCP server. Static IP addresses are typically used for devices that need to be accessible from outside of the local network, such as web servers or file servers.

There are a few advantages to using a static IP address. First, it can make it easier to access devices from outside of the local network. Second, it can improve performance, as devices with static IP addresses do not need to go through the DHCP process to obtain an IP address. Third, it can provide more security, as devices with static IP addresses can be more easily configured with firewalls and other security measures.

However, there are also a few disadvantages to using a static IP address. First, it can be more difficult to manage, as you need to manually configure the IP address on each device. Second, if the device loses its connection to the network, it will not be able to obtain a new IP address automatically. Third, if the network is reconfigured, the static IP addresses of devices may no longer be valid.

How to find your current IP address on Ubuntu

There are a few ways to find your current IP address on Ubuntu.

• The easiest way to find your IP address is to use the terminal. To do this, open the terminal and type the following command:

“`
ip addr show
“`

This will display a list of all of the network interfaces on your system, along with their IP addresses.

• You can also find your IP address in the NetworkManager settings. To do this, open the Settings app and go to Network. Under the Wired or Wireless tab, you will see your IP address listed.

• Finally, you can also find your IP address in the command-line interface (CLI). To do this, open the CLI and type the following command:

“`
hostname -I
“`

This will display your IP address.

How to configure a static IP address on Ubuntu

To configure a static IP address on Ubuntu, you will need to edit the `/etc/netplan/01-netcfg.yaml` file. This file contains the network configuration for your system.

To open the file, use the following command:

“`
sudo vi /etc/netplan/01-netcfg.yaml
“`

Once the file is open, you will need to find the section that corresponds to your network interface. For example, if you are using a wired connection, the section will be called `ethernets`.

To configure a static IP address, you will need to add the following lines to the section:

“`
address:
netmask:
gateway:
“`

For example, if your IP address is `192.168.1.100`, your netmask is `255.255.255.0`, and your gateway address is `192.168.1.1`, you would add the following lines to the section:

“`
address: 192.168.1.100
netmask: 255.255.255.0
gateway: 192.168.1.1
“`

Once you have added the lines, save the file and exit the editor.

To apply the changes, run the following command:

“`
sudo netplan apply
“`

Your static IP address should now be configured.

What is a static IP address?

A static IP address is a permanent IP address that is assigned to a device on a network. This means that the device will always have the same IP address, regardless of whether it is connected to a different network or not. Static IP addresses are typically used for devices that need to be accessible from outside of the local network, such as web servers and file servers.

Why would you want to use a static IP address on Ubuntu?

There are a few reasons why you might want to use a static IP address on Ubuntu.

• To make your device accessible from outside of your local network. If you want to be able to access your device from another computer on the internet, you will need to assign it a static IP address.
• To avoid IP address conflicts. If you have multiple devices on your network that are using DHCP to obtain IP addresses, it is possible that they will end up with the same IP address. This can cause problems with networking. By assigning a static IP address to your device, you can avoid this problem.
• To improve performance. In some cases, using a static IP address can improve the performance of your device. This is because the device will not have to go through the process of obtaining a new IP address from the DHCP server each time it is connected to the network.
