View Curriculum
  • Students will need a basic understanding of Networks
  • Students will need a simulator/emulator to go along with the course
  • Students can follow along with my book (available on AMAZON), called "The Only IP BOOK YOU Will Ever Need!
  • Students should have a great desire to know this protocol, not only for certification purposes, but also for the real world

This course will cover all aspects of IPv4. Students will learn IP addressing, Subnetting, VLSM, Route Summarization, Wildcard Masking, common Network equipment, basic Router administrative commands, configuring Router interfaces, planning a Network infrastructure and many other topics that are important and needed, not just for certification purposes, but also for real world scenarios. 

The course will also show students how to assign IP addresses to PC’s and Routers. As well as gaining an understanding of the TCP/IP properties such as gateways.

DISCLAIMER:   Please note that the simulators/emulators used in this course are not part of the course. It is the students responsibility to have these to practice with. The Cisco Packet Tracer and/or VIRAL (Virtual Internet Routing Lab) are Cisco proprietary software and can only be obtained through Cisco. It is up to each student to obtain the simulator/emulator of their choice to study along with this course. Students have other options like GNS3, BOSOM or Live Equipment.

This is a lecture based course using hands on labs. 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 IPv4 course will help you in becoming comfortable with, not only with the IPv4 protocol, but it will also help you in preparing for any networking certification and Computer Science Degree; not to mention the fact, that for those that are going for a Cisco certification exam, it will help you in calculating IP addresses without a calculator, since a calculator is NOT allowed in a testing site.. This method should expedite the way you convert in order to make you faster, better and stronger to pass the test!

Please be aware that I have authored a book on IPv4 that is available on AMAZON called "The Only IP Book You Will Ever Need!". For those interested, this book along with this course, will help you achieve a greater understanding of this still relevant protocol.

2017 will be the year to achieve your goals!

If you are determined, ambitious and hungry for a new beginning...then 2017 should be your year!  

...and how better to start or end the year than to get an IT Certification!

Whether you are interested in the CCNA R/S, the CCENT, ICND2, the CCNP, CompTIA or Microsoft certifications; or maybe you just want to understand the key topics for these, taking one or ALL of my courses, will get you a lot closer to that goal.

But, don't take my word for it...please take a look at the FREE previews (they are available in all my courses) and see for yourself.

As for me, 2017 will be the year of putting out new courses for different types of IT certifications among other things.

Expect to see more courses on Cisco, Microsoft, CompTIA to name a few.

I also hope to complete my second book based on ALL the Routing Protocols either at the end of 2017 or by the first quarter of 2018.

However, keep in miind that my first book is currently available on AMAZON and it's called "The Only IP Book You Will Ever Need!" This is for those that may need a little help in understanding IP's since it is the key topic to Networking and IT in general.

So, yes, with all these great plans for the near future, my schedule will be quite full but fulfilling!

Now...what you wanted to know about me but where afraid to ask:

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 many years in the field and in the teaching industry. I hold the following certifications: CCNA, CCNA Security, CCNA Voice, CCNP, Security+, Network+, A+, MCP, MCTS & MOS and since then, I have passed the first of the required 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 that I also do private consulting.

Now, I bring the classroom to you by being in several e-Learning platforms world-wide, teaching over 100K students...courtesy of the internet. Thank goodness for technology!   ;-)

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 you, the student. I know first hand what you have been exposed to as opposed to what you 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 your rejection of the Status Quo.

I have taught corporate employees at MetroPCS (now T-Mobile) and have also taught IT professionals of companies like The Florida Marlins, Ulysse Nardin, Alberta Water Department (Canada), The Assurant Group, Hospital personnel & Attorney's firms, among others. to guide them in acquiring their IT certifications or general knowledge. 

However, my expertice also extends to being able to teach applications as well. YES!...I am also an applications instructor and qualified to teach Word, Excel, PowerPoint and Access.This of course includes the MOS (Microsoft Office Specialist) certification.

As you can see, I am a multifaceted person and consider myself to be an eternal student as well.

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,  Microsoft or CompTIA 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 that you, the student, is prepared for a job interview and/or maintaining your current job by enhancing your skills. This is where I step in and make sure that you are prepared for whatever you need and make you an asset to your 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. I truly believe in "KISS",,,NO, I don't want to kiss you, what this means "keep it simple stupid" - If things are kept simple, easily 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 physics jargon or mumbo jumbo in my teachings. My courses are very interactive and extremely dynamic! 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. ;)

I certainly hope that after a careful review of my credentials & testimonials (you can Google it you know!), I'm the Cisco, Microsoft or CompTIA Instructor you're looking for!
