What role does a DHCP server play in a network?

A DHCP (Dynamic Host Configuration Protocol) server plays a crucial role in assigning IP addresses to devices on a network. Its primary function is to automate the process by which devices obtain IP addresses when they connect to a network. This is important because every device needs a unique IP address to communicate effectively within the network and to reach the internet.

When a device joins a network, it sends a request to the DHCP server, which dynamically assigns an available IP address from a configured range (also known as a scope) and sends back the necessary configuration information. This process simplifies the management of IP addresses and reduces human error associated with manually assigning IP addresses. Overall, the DHCP server enhances network efficiency by managing IP address assignments, ensuring devices can connect seamlessly without conflicts.
