What is the basic function of DHCP (Dynamic Host Configuration Protocol)?

The basic function of DHCP, or Dynamic Host Configuration Protocol, is to automatically assign IP addresses and network configurations to devices on a network. This process simplifies network administration by allowing devices to join a network seamlessly without needing manual configuration. When a device connects to a network, it sends out a request to the DHCP server, which responds with an available IP address and other configuration information, such as subnet mask, default gateway, and DNS server addresses.

By utilizing DHCP, network administrators can reduce errors and ensure that IP addresses are managed efficiently. This automatic assignment helps prevent IP address conflicts and allows for easier updates to network configurations, as administrators can change settings centrally on the DHCP server rather than accessing each device individually.

In contrast to the other options, managing static IP addresses requires manual configuration, enhancing network security typically involves different protocols and measures, and analyzing network performance is usually done using different tools and protocols focused on monitoring and measurement rather than configuration.
