IPv4 Tutorial: Everything You Need!

   Watch Promo

7 Hours of Training


This course is over 6 hours in length and will cover all aspects of IPv4. Students will learn IP addressing, Subnetting, VLSM, Route Summarization, and Wildcard Masking. The course will also show students how to assign IP addresses to PC's and Routers. Students will gain an understanding of the TCP/IP properties such as gateways, DNS, WINS, and the use of alternate addresses.

This is a lecture based course using a whiteboard and hands on labs using Cisco's Packet Tracer. My method will make you feel like you are sitting in a classroom environment and give you some hands on experience.

Handouts and labs will be available to facilitate learning and practice.

My IP course will help you in becoming comfortable with, not only IPv4, but it will also help you in preparing for any networking certification and Computer Science Degrees; not to mention the fact, that for those that are already working in the field, it will help you in calculating IP addresses without a calculator. This method should expedite the way you convert in order to make you faster, better and stronger!


"After struggling with subnetting again and again using countless methods/tricks/etc I finally "saw the light" after taking this course! I can't do it all in my head, yet, but now feel real confident when tackling the calculations and spend less than half the time that I did with any other method I've tried! Excellent course all the way around!!"

- Jeff McCormick

"I really enjoyed this IP addressing course. Laz breaks down all of the information in a very simple way. I watched his Youtube video which was very good and decided to buy this course. I'm very happy that I did. There are no overly complicated formulas and his way of explaining is like listening to one of your friends talk. No instructor talking over your head stuff. He instructs like a regular guy who just happens to be an expert with IPV4."

If you are tired of the same old methods of learning and want someone that is pretty much unconventional, but at the same time will provide you with an enjoyable learning experience in layman's terms...then please preview my courses and you will discover that I am your guy.

I am a Network Engineer with over 15+ years in the field and in the teaching industry. I hold the following certifications: CCNA, CCNA Security, CCNA Voice, Security+, Network+, A+, MCP, MCTS & MOS and I just passed the first of two test for the CCIE!

My teaching experience stems from teaching at institutions like Palm Beach Community College, New Horizons, Florida Career College (now Anthem College) and The Academy of South Florida, not to mention teaching at my own training facility in Miami, Florida.

Having been in all sides of the spectrum; as a student, a teacher/trainer, and in the field, I believe this uniquely qualifies me to understand the student, and what they have been exposed to as opposed to what they really want to accomplish. These two are sometimes extremely conflicting and frustrating. That is why I teach in the manner I do and can relate to the student's rejection of the Status Quo.

I have taught corporate employees at MetroPCS (now T-Mobil) and have also taught IT professionals of companies like The Florida Marlins, Hospital personnel & Attorney's firms amongst others to be able to acquire their CCNA certification and/or their Microsoft certifications; like the MOS (Microsoft Office Specialist). YES!...I am also an applications instructor and also teach Word, Excel, PowerPoint and Access.

I teach in an unconventional way that allows for students to understand the subject matter and can therefore, not only prepare them for a Cisco and/or Microsoft certification exam, but apply my methods in the real world. I strive to give the student a greater opportunity to compete in the current job markets. Do I go above and beyond what is needed for a certification?...YES, I do!...because it's not only about getting a certification, it's also about making sure the student is prepared for a job interview and/or maintaining their current job by enhancing their skills. This is where I step in and make sure that the student is prepared for whatever they need and make them an asset to their employer. Everyone has different requirements and I make sure, or at least I try, to provide information for most scenarios.

My classes and/or courses are very simple and that's how I like to teach. If things are kept simple, easy and explained in a way that the student can grasp quickly and retain the information...then I have achieved my goal!

For those that do not know me yet, you may not be used to my style of teaching, but you will soon get accustomed to it :)... I'm very laid back, I try to make learning fun and I teach in layman's terms...no physics jargon or mumbo jumbo in my teachings. My courses are very interactive and extremely dynamic!...you will not find my lectures monotone or boring, because falling asleep, for lack of excitement, is just NOT an option. Just take a look for yourself at my video previews, which I always provide on ALL my courses, so you can determine if I'm the right guy to help you get your industry specific certifications. ;)
