Title: Did NOT meet my expectations!
Review: This book is good except for one very important aspect of TCP/IP: subnet masking. The author(s) gave very little explanation on determining a mask for a range of IPs. They mention in one paragraph about using more than one octect to determine a mask, but fail to give any detailed explanation. I used other books to get a thorough understanding. I'm not a novice. I've been working in IT for eight plus years. Try an O'Reilly book instead!
