"⭐⭐⭐⭐⭐ ""OUTSTANDING Explanation and Resource!"" ""Bought this tonight after watching videos and reading the Network Text for College course in TCP/IP and could not get a good grasp through my assigned textbook. Looked up some websites for tutorials, practice pages, etc but they weren't giving me the understanding. I found this book and figured ""What could I lose for a few bucks"" and Man is it worth the $. I wish this guy wrote my textbook!!! Ramon, this is awesome. Outstanding explanation of network subnetting. I took a break and had to write this!!! Thank you!! btw I grabbed your other books also. I'm making a transition to IT from a prior career. This will definitely help on the journey!"" - Ray Temt ⭐⭐⭐⭐⭐ ""Love it!"" ""Very good materials and straight to the point."" - Tam Nguyen ⭐⭐⭐⭐⭐ ""Excellent book"" ""It's easy to understand and very helpful."" - Orlando A. ⭐⭐⭐⭐⭐ ""Straight to it"" ""I have some background in IT so I find it easy to read, someone new to the field might need to read a couple of times and practice to understand."" - Carlos A. Ayuso ⭐⭐⭐⭐⭐ ""Excellent buy"" ""This book was EXACTLY what I needed. Straight and to the point, not too wordy and very easy to understand."" - Loyda Rivera"
