DHCP Ports 67 and 68 Explained: How DHCP Works

DHCP (Dynamic Host Configuration Protocol) automates IP address assignment to devices on a network, simplifying network management and reducing errors. It utilizes UDP ports 67 (server) and 68 (client) to facilitate communication through a four-step process called DORA – Discover, Offer, Request, and Acknowledge – where the client initially broadcasts a request and the server responds with an IP configuration. Relay agents can extend DHCP services across different network segments, and understanding these ports is crucial for maintaining network reliability and security.
