How to set DHCP on Ubuntu 25.04 ?

A DHCP server automatically assigns IP addresses to devices on your network. Ubuntu 25.04 makes this easy with the isc-dhcp-server package.

Step 1: Update Your System

Always start by updating the package index:

sudo apt update && sudo apt upgrade -y

This ensures you’re installing the latest packages.

Step 2: Install the DHCP Server Package

Ubuntu uses ISC DHCP server, which is reliable and widely supported:

sudo apt install isc-dhcp-server -y

The installation will add the DHCP server service to your system.

Step 3: Verify Installation

Check that the isc-dhcp-server package installed correctly:

dhcpd --version

You should see the version number, confirming the server is available.

Step 4: Enable the DHCP Service

Start and enable the DHCP service so it runs on boot:

sudo systemctl enable isc-dhcp-server
sudo systemctl start isc-dhcp-server

Step 5: Check Service Status

Make sure the DHCP service is running properly:

sudo systemctl status isc-dhcp-server

You should see an “active (running)” status if everything is correct. At this point, the DHCP server is installed on Ubuntu 25.04 and ready for configuration when needed.
