Introduction
Welcome to our comprehensive guide on configuring DHCP server Ubuntu! In today’s digital age, networks have become an essential part of our lives. DHCP (Dynamic Host Configuration Protocol) is a networking protocol used to assign IP addresses and other network configuration parameters to devices on a network. It automates the process of assigning IP addresses and configuration parameters, making network management easier and more efficient.
However, configuring DHCP server Ubuntu can be a daunting task, especially for beginners. In this article, we will walk you through everything you need to know about configuring DHCP server Ubuntu from scratch.
From setting up a DHCP server to configuring its advanced settings, we got you covered. Let’s dive in and explore the world of DHCP server Ubuntu!
What is DHCP Server?
DHCP server is a networking service that automatically assigns IP addresses and other network configuration parameters, such as subnet masks, default gateways, and DNS servers, to devices on a network. It simplifies the process of network administration by eliminating the need for manual configuration of network settings on each device.
DHCP server is used in both small and large networks and can be configured on various operating systems like Windows, Linux, Unix, and Mac OS X. In this article, we will focus on configuring DHCP server Ubuntu.

Step 1: Installing DHCP Server Package
The first step in configuring DHCP server Ubuntu is to install the DHCP server package. You can do this by running the following command:
sudo apt-get install isc-dhcp-server
Step 2: Configuring Network Interfaces
Next, you need to configure your network interfaces. To configure your network interfaces for DHCP server Ubuntu, you need to edit the /etc/network/interfaces file.
Step 3: Configuring DHCP Server Settings
After configuring your network interfaces, you need to configure the DHCP server settings. You can do this by editing the /etc/dhcp/dhcpd.conf file.
Step 4: Starting the DHCP Server Service
Once you have configured the DHCP server settings, you need to start the DHCP server service. You can do this by running the following command:
sudo service isc-dhcp-server start
Step 5: Testing DHCP Server Configuration
Finally, you need to test your DHCP server configuration to ensure that it is working correctly. You can do this by using a DHCP client to obtain an IP address and other network configuration parameters automatically from the DHCP server.
Advanced DHCP Server Configuration Settings
Configuring DHCP server Ubuntu also allows you to configure advanced settings, such as:
- Setting up DHCP failover
- Configuring DHCP reservations
- Limiting lease time for IP addresses
