What is the function of a DHCP server?

The function of a DHCP (Dynamic Host Configuration Protocol) server is to assign IP addresses to devices on a network automatically. This process streamlines network management by eliminating the need for manual configuration of IP addresses for each device. When a device connects to the network, it sends a request to the DHCP server, which responds with an available IP address and other necessary network configuration parameters, such as the subnet mask and default gateway.

This automatic assignment ensures that each device receives a unique IP address, thereby preventing address conflicts that can arise if IP addresses were assigned manually. Additionally, DHCP can support various types of network configurations, making it a flexible solution for both small home networks and larger enterprise environments.
