Acknowledgements I would like to thank my wife
Digna, for her unfaltering support and for believing in me, even in times where I doubted myself. My beautiful wife was the true force behind making this book a reality. She was always by my side every step of the way pushing and motivating me. Her unconditional love is what catapulted me into doing things that I would have only imagined...and writing this book was one of those things.
I would also like to thank my mother Orquidea, for constantly letting me know that I could accomplish great things and encouraged me to move forward. My mother has always believed in me and also provided me with unconditional love. She has always been present when Ive needed her and has given me the encouragement to believe in myself and to never look back at what was, but rather look forward at what can be. This she did despite the headaches I gave her and sometimes still do. She has always sacrificed her own livelihood to give me an opportunity of a better future.
This book is dedicated to the two wonderful ladies in my life whom without, this book would not have been possible. - Laz

Introduction
Im sure some of you are somewhat perplexed and asking Laz, why are you writing a book on IPs when so many books and websites exist on the subject? Well, the answer is simple, I want to get rid of any web of confusion you may have on this particular
subject.
IPs have been explained in so many ways that it would take me hundreds of chapters to try and unravel that which has been so unnecessarily
raveledand Im not about to go through all that work, mainly because I dont want to.
So, after much thought, I decided to put it down in plain text and explain my method, which is the simplest and easiest method available. But w hy Laz? you might ask. Well, I wanted you to understandwait! Let me rephrase that I needed you to understand everything that has to do with IPs. After all, they dont call me The IP Master for nothing.
Hopefully, this book will be the one that will finally fill in all those missing gaps you may have about this much misunderstood subject. However, if this is the first time you read a book on IPs, then you should be pre-
warned; you should expect to gain great understanding and a strong foundation of the IP protocol when you read this book; both on IPv4 and IPv6 . So, if this is what you are hoping to achieve, I believe you have come to the right place.
My IP book will not only help you with the IP part of your Cisco certification, but it will also help you in passing any test you may take in dealing with this subject matter. At the very least, it will let you impress your boss or co-workers when you start subnetting in your heador fingers. Yes! This book will let you do just that.
Ive been told that besides Networking many other fields within the scope of IT and Technology need to deal with IPs as well. My sincere goal is for you to carry the knowledge you will have learned here and have the ability to transfer it onto your current or future work environment; making you a greater asset to any institution and/or corporation.
Like I mentioned before, this book is written in a very simplistic and easy to understand manner (You will NOT find any IP book in the market today that is easier, straightforward, more clear-cut and precise than this one!). I call the process of understanding IPs Journeys , since in my view, this is an adventurous trek to finally reach full comprehension and demystify the whole concept surrounding IPs.
Our first journey will begin with the basics of IPv4. Then, we will work our way into addressing end-devices, switches & routers. From there, we will maneuver our way slowly into the subnetting of an IP Address; both class-full and class-less . This book will then take you into the
summarization part of IPv4; explaining the importance of it and of course, how to summarize networks.
We will then round off IPv4 with wildcard masking; which you normally use in configuring OSPF, NAT and of course, your access-list.
If youre thinking Laz, its just too much information man! dont worry, I have your back on this one ;) In this book I will explain all these topics thoroughly. I will break it down for you in a way that you will have no choice than to understand and comprehend the material. So, expect to see plenty of illustrations and practices within. This, I have done, so you can
gain a full understanding of the subject as discussed herein.
Once we are done with the IPv4 portion of the book, we will dive into the now infamous IPv6 protocol yes , finallywhat weve all been waiting for!!! This, to me, is extremely exitingI feel like a kid contemplating my favorite candy! By now youre probably shacking your head arent you? But I assure you that you will learn its terminology, its format, the diverse sections of it, and learn about the different types of addresses that exist within IPv6 and the benefits that it brings to the world. And yeshow can we forget about the transition
mechanisms that this protocol has to offer as well?
The way I see it, no matter how bad we may want to desperately transition to IPv6 ( at least I do ); we will still be dealing with IPv4 and will continue to do so for quite a while into the future. So, there is no going around it guys and gals, we cannot cut corners here.
We have to learn how to configure both protocols so they can work and co-exist with each other for some time to come. So, dont hold your breath for IPv4 to go away any time soon.
Now tell meare you as excited as I am? This is truly my favorite subject and I hope it comes across in this book.
But lets move on ( I tend to digress a bit, and youll find this out throughout the book. ); once you acquire a good understanding of the terminology and how to identify a proper IPv6 address, we will finally get to the fun part of
SUBNETTING! Doc you are insane ! ... Nope ! I assure you that you will be subnetting in IPv6 and you will not be using any complicated formulas or any type of physics to do it.
Those of you that know me, should know by now that it is not for me, and I believe or hope, that its not for you either; otherwise, why get this book?
Let me start by confessing somethingI dont like math and never have, and no one is going to convince me that the complicated formulas that are currently used are easier than the method Im about to show you in this book.
Now, if you DO like math and love to work with formulas, then knock yourself out. Easy is not for everyone you know. But for those like myself, that are always looking to reach the correct answer in the fastest and simplest of forms, then this is the book for you.
Yes, we all know that a calculator is faster and you dont have to think but in a testing environment, you are NOT allowed to use one. Please, take my word for it. You will be removed from a testing site if you try to take a calculatortrust me on this. I have perfected this method so that I can make life easier for you.
This is the only method where you will be able to do any IP addressing and subnetting in your head and therefore have a greater chance to pass your CCNA certification exam. After all, that is the goal isnt it?
You should know by now that by the time you finish this book, you will be doing IP addressing in your head; and I repeatwithout a calculator! After all, this is mainly intended to take a certification exam. Once you get your certification and/or pass your exam, then using a calculator wont be an issue. Go right aheaduse a calculator all day long; in fact, I encourage you to use a calculator to verify what you will have learned here.
