Episode 63 — MAC Address Concepts — Identification and Network Access
This episode explores the role of Media Access Control (MAC) addresses as unique identifiers for network interfaces. We explain how MAC addresses are assigned at the hardware level, how they are used in Layer 2 network communication, and how they can be filtered or whitelisted for access control. The discussion includes how MAC addresses appear in server NIC configurations and how they are referenced in network documentation.
Practical and exam-relevant examples cover scenarios such as using MAC address filtering on a switch to restrict device access, or verifying the MAC address of a NIC when troubleshooting connectivity. We also discuss potential pitfalls, such as MAC spoofing, and how to detect and mitigate such risks. A solid understanding of MAC address concepts ensures candidates can manage network access controls effectively in both secure and high-availability environments.
