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.
