What role does a DHCP server play in a network?

A DHCP server, which stands for Dynamic Host Configuration Protocol server, plays a crucial role in managing IP addresses within a network by automatically assigning dynamic IP addresses to devices. This process simplifies network management, especially in environments where devices frequently join or leave the network, such as in a corporate office or public Wi-Fi area.

When a device connects to the network, it sends a request to the DHCP server for an IP address. The server then selects an available IP address from a predefined pool and assigns it to the device for a specified lease period. This automatic assignment helps prevent IP address conflicts, where two devices could unintentionally end up with the same IP address.

Other options like static IP address assignment, managing network devices through a web interface, and monitoring network security do not accurately represent the core functionality of a DHCP server. Static IP addresses are typically assigned manually and are not managed by DHCP, the web interface aspect pertains to network management systems, and security monitoring involves different tools and protocols separate from DHCP’s primary role of IP address assignment.
