What is the function of DHCP in a network?

The function of DHCP, or Dynamic Host Configuration Protocol, in a network is to assign IP addresses to devices dynamically. When a device connects to a network, it requires an IP address for communication. Instead of having a network administrator manually assign IP addresses to each device, which can be time-consuming and prone to errors, DHCP automates this process. It allocates IP addresses from a predefined pool to devices as they connect, ensuring that each device has a unique address for the duration of its connection. This dynamic assignment also makes it easier to manage IP address allocation efficiently, as it can reclaim addresses that are no longer in use and assign them to new devices.

Monitoring network traffic, managing firewall settings, and encrypting network communications, while important networking functions, do not fall under the purview of DHCP. Each of these tasks is handled by different specialized protocols and systems designed for their specific purposes.
