	Page 485 Number of nets table	Hi, this is a minor error. I've learned a lot from this book! The minor mistake (I suppose): the paragraph "You can compute the number of nets as follows..." Appendix C has the following multiplication: Clas B: 64 * 256 = 16128 I suppose it should be 16384, instead of 16128. Again, this is a minor mistake. This book is amazing. Congratulations! Love from Brazil, Osmar Gomes Note from the Author or Editor: You are correct, although this error is on p. 485 of the First Edition, not the Second Edition. Good catch! The line about Class B networks (near the bottom of the page, about 5 lines up from the bottom) should read: * Class B: 64 * 256 = 16,384	Osmar Gomes de Sousa	Apr 03, 2022
