Episode 33: Networked Host Services — DHCP, DNS, Print, AAA

Host services are critical to how devices function on modern networks, and this episode explains the most essential ones covered on the exam. We begin with D H C P—how it dynamically assigns IP addresses, leases, and default gateway information to network clients. Then we move to D N S, which translates domain names into IP addresses and plays a key role in nearly every web-based application.We also explore common print services and discuss authentication and authorization systems, commonly referred to as AAA. Understanding how these host services operate and interact is essential when diagnosing network functionality or resolving end-user issues. These services are often presented in multi-layered exam questions, so we break them down clearly to improve your analytical skills and recall. Brought to you by BareMetalCyber.com.
