What Is DHCP?

Dynamic Host Configuration Protocol — automatic IP assignment.

Definition

DHCP automatically assigns IP addresses, gateways, DNS servers, and other configuration to devices on a network.

Example Flow


Device → "I need an IP"
DHCP Server → "Use 192.168.1.50"
Device → config applied

Why It Matters

Without DHCP, every device would require manual IP configuration, leading to slower setups and more errors.
