There are 3 modules in this course

Master the addressing and routing skills at the heart of every network you will ever work on. Through the industry-proven lens of the CompTIA Network+ (N10-009) exam, this course starts with TCP/IP addressing from the ground up, including binary math, subnet masks, and CIDR subnetting, then explains how routers work, NAT, port forwarding, and the major dynamic routing protocols: OSPF, BGP, EIGRP, and FHRP. Multiple subnetting scenarios build real fluency rather than memorized formulas, and online labs reinforce IP configuration and routing tasks.

Not planning to take the exam? IP addressing and routing are skills network professionals use every day, so they apply on the job whether or not you pursue the certification. You'll understand how packets travel across networks and how to configure and troubleshoot addressing. The first module is designed as an accessible entry point, and expert instruction with practical examples helps you build confidence step by step. You'll finish able to subnet networks and explain how routers move traffic between them.

This chapter is a guide to IP addressing, covering how addresses, subnetting, ARP, DHCP, and common addressing issues work together to keep networks communicating smoothly.

Frequently asked questions

A: It covers IPv4 and IPv6 addressing, subnetting and CIDR, NAT, static routing, and dynamic routing protocols including OSPF, BGP, EIGRP, and FHRP.

A: Familiarity with networking fundamentals, including the OSI model, cabling, and network topologies.

A: The course includes about 4 hours of material: videos, quizzes, and optional assignments. How long it takes you depends on your starting knowledge and how you like to study, so here are some typical ranges. If you already have experience with these topics, you may finish in about 3 to 4 hours by skimming familiar lessons. If you have some background, plan on about 4.5 to 6 hours. If you are new to the topic, plan on about 6 to 8 hours, because you may want to rewatch lessons and review quizzes. At the recommended 4 to 5 hours per week, this works out to about 1 to 2 weeks. The course is self-paced, so you can rewatch any lesson as often as you need.

To access course materials, assignments, and earn a Certificate, you'll need to purchase the Certificate experience when you enroll in a course. Eligible learners may also have the option to start with a Free Trial. Some courses may also offer a Full Course, No Certificate option. This lets you access course materials, submit required assessments, and receive a final grade, but you won't be able to earn or purchase a Certificate.
