What is the purpose of DHCP in a network and how does it work?

Understanding the Purpose of DHCP in a Network

DHCP, which stands for Dynamic Host Configuration Protocol, plays a crucial role in network administration. It is a network protocol that automatically assigns IP addresses and other network configuration settings to devices connected to a network. This automation simplifies the administration of IP addresses within a network, saving time and reducing the risk of configuration errors.

How DHCP Works:

When a device connects to a network, it broadcasts a DHCP request packet to discover a DHCP server. The DHCP server then responds with an available IP address and other network settings based on the configuration of the DHCP server. This process of automatically assigning IP addresses is known as DHCP lease allocation with a specific lease time, after which the IP address may be reassigned to another device.

Overall, DHCP simplifies network administration by automating the process of IP address allocation and configuration, making it easier for network administrators to efficiently manage IP addresses within their network infrastructure.
