DHCP (Dynamic Host Configuration Protocol) is a fundamental networking protocol that allows devices to automatically obtain IP addresses and other network configuration parameters. In the context of Raspberry Pi, DHCP plays a crucial role in simplifying network setup and management, making it an essential topic for every Raspberry Pi enthusiast.

Raspberry Pi, being a versatile and widely used single-board computer, fully supports DHCP functionality. However, there are certain adjustments and considerations specific to the Raspberry Pi environment that we will explore in this article.

Examples:

1. DHCP Server Configuration:

   • Install the DHCP server software on your Raspberry Pi by running the following command:

     sudo apt-get install isc-dhcp-server

   • Configure the DHCP server by editing the "/etc/dhcp/dhcpd.conf" file. Customize the IP address range, lease duration, and other parameters according to your network requirements.

   • Restart the DHCP server to apply the changes:

     sudo service isc-dhcp-server restart

2. DHCP Client Configuration:

   • Raspberry Pi is typically set up as a DHCP client by default. However, you can manually configure a static IP address if needed.

   • To configure a static IP address, open the "/etc/dhcpcd.conf" file and add the following lines at the end:

     interface eth0
     static ip_address=192.168.1.10/24
     static routers=192.168.1.1
     static domain_name_servers=192.168.1.1

   • Save the file and restart the Raspberry Pi for the changes to take effect:

     sudo reboot
