What is the primary function of a DHCP server in a network?

The primary function of a DHCP (Dynamic Host Configuration Protocol) server is to assign IP addresses to client devices dynamically. When a device connects to a network, it needs a unique IP address to communicate with other devices. The DHCP server automates this process by dynamically allocating an IP address from a predefined range, known as a DHCP scope, ensuring that each device receives a unique address without manual configuration.

This dynamic assignment simplifies network management, especially in environments with many devices, as it eliminates the need for a network administrator to assign IP addresses individually. Additionally, the DHCP server can send other necessary configuration information to the client devices, such as the subnet mask, default gateway, and DNS server addresses, which aids in their proper configuration for network access.

Other functions mentioned, such as managing routing, providing network security, and controlling bandwidth allocation, are handled by different network components and protocols, not the DHCP server. The focus of DHCP is primarily on the allocation and management of IP addresses within a network.
