Episode 41: Introduction to IP Addressing and Subnetting
This episode introduces the fundamentals of IP addressing and subnetting, two of the most critical skills for the Network Plus exam. It explains how IP addresses ident...
Episode 42: Public vs. Private Addressing — What You’re Allowed to Use
This episode explains the difference between public and private IP addresses and why the distinction is important for both exam and real-world environments. Public add...
Episode 43: NAT — Hiding Networks Behind a Single IP
This episode introduces Network Address Translation (NAT), a process that allows multiple internal devices to share a single public IP address. It explains the core fu...
Episode 44: PAT — Port Address Translation and Overload NAT
This episode focuses on Port Address Translation (PAT), often called overload NAT, which extends NAT by allowing multiple devices to share one public IP using differen...
Episode 45: APIPA and EUI-64 — Self-Assigned and Extended Addressing
This episode introduces Automatic Private IP Addressing (APIPA) and EUI-64 addressing. APIPA is a fallback mechanism in IPv4 where devices assign themselves an address...
Episode 46: IPv4 vs. IPv6 — A Structural Comparison
This episode compares IPv4 and IPv6, highlighting their structural differences and why both remain important on the exam and in practice. IPv4 uses 32-bit addressing, ...
Episode 47: IPv6 Address Types — Know the Modes of Delivery
This episode introduces the different types of IPv6 addresses, which define how communication occurs within an IPv6-enabled network. The three main categories are unic...
Episode 48: The Default Gateway — Directing Traffic Outward
This episode explains the role of the default gateway, which directs traffic from a local network to destinations outside its subnet. Without a properly configured gat...
Episode 49: Understanding Classful IPv4 Addressing
This episode reviews classful IPv4 addressing, a historical system that divided addresses into five classes: A, B, C, D, and E. Each class had predefined ranges and de...
Episode 50: Classless Addressing and VLSM
This episode introduces classless addressing and Variable Length Subnet Masking (VLSM), which replaced the limitations of classful addressing. Classless addressing all...
Episode 51: CIDR Notation — Reading and Writing Network Ranges
This episode introduces Classless Inter-Domain Routing (CIDR) notation, the shorthand system used to represent IP address ranges with a suffix indicating the subnet ma...
Episode 52: IPv4 Subnetting — The Process Step by Step
This episode walks through the process of IPv4 subnetting, a skill that requires practice and speed for the exam. It explains how to take a given network address and d...
Episode 53: IPv6 Subnetting and Address Planning
This episode covers IPv6 subnetting, which operates differently from IPv4 due to its larger 128-bit address space. Instead of conserving addresses, IPv6 subnetting foc...
Episode 54: IPv6 Transition Technologies
This episode introduces IPv6 transition technologies, which allow networks to support both IPv4 and IPv6 during the migration period. Methods such as dual-stack, tunne...
Episode 55: Virtual IPs and Subinterfaces — Logical Address Extensions
This episode explains the concepts of virtual IPs and subinterfaces, which extend logical addressing capabilities. A virtual IP is an address shared among devices, oft...
