A Static IP (Internet Protocol) is a fixed IP address assigned to a device, such as a computer or a router, that does not change over time. Unlike a dynamic IP address, which can change each time a device connects to the internet, a static IP address remains the same until it is manually changed by the user or the internet service provider.
Static IPs are commonly used for servers, websites, or other devices that require a consistent and reliable internet connection. They can also be useful for remote access or online gaming, where a fixed IP address is necessary for connecting to a specific server or network. Static IPs are typically provided by internet service providers for an additional fee, and may require specific network configurations to set up and maintain.
Configuring a Static IP on Ubuntu Server 23.04
we understand that configuring a static IP address on your Ubuntu Server 23.04 can be a crucial step in maintaining your server’s stability and accessibility. In this article, we will provide you with a comprehensive guide on how to configure a static IP on your Ubuntu Server 23.04.
Step 1: Identify Your Network Interface
The first step in configuring a static IP address on your Ubuntu Server 23.04 is to identify your network interface. To do this, you can use the command ifconfig -a in your terminal. This will display a list of network interfaces available on your server.
Step 2: Edit Network Configuration File
Once you have identified your network interface, you will need to edit the network configuration file. You can do this by navigating to the /etc/netplan/ directory and opening the configuration file using your preferred text editor.
Step 3: Configure Static IP
To configure a static IP address, you will need to modify the configuration file and set the IP address, gateway, and netmask for your network interface. Here’s an example of what your configuration file might look like:
yaml
Copy code
network: version: 2 renderer: networkd ethernets: enp0s3: addresses: – 192.168.1.100/24 gateway4: 192.168.1.1 nameservers: addresses: [8.8.8.8, 8.8.4.4]
In this example, we have set the static IP address to 192.168.1.100, the gateway to 192.168.1.1, and the netmask to 24. Additionally, we have set the nameservers to 8.8.8.8 and 8.8.4.4, which are Google’s public DNS servers.
Step 4: Apply Changes
After you have made the necessary changes to the configuration file, you will need to apply them by running the command sudo netplan apply. This will apply your changes and restart the network service.
Step 5: Verify Configuration
To verify that your static IP address has been configured correctly, you can use the command ip addr show. This will display your network interface configuration, including the IP address, netmask, and gateway.
