دانلود کتاب Understanding TCP/IP Subnetting

یکی از مواردی که در آدرس دهی IP بوسیله آدرس های کلاس A و B مطرح می باشد ، چگونگی طاراحی سیستم آدرس دهی شبکه برای هدر نرفتن آدرس های IP است. در شبکه های که از TCP/IP استفاده می کنند حداکثر می توان ۳۰۰ تا ۵۰۰ عدد دستگاه را جای داد. اگر بیشتر از این تعداد دستگاه را در یک Broadcast Domain قرار دهیم ف مشکلات مربوط به BroadCasting رخ خواهد داد این تعداد را می توان با به کار بردن یک یا دو کلاس C آدرس دهی کرد اگر از کلاس A استفاده کنیم با این که فقط یک کلاس A را می توان برای آدرس دهی این تعداد به کار برد ولی در این صورت تعداد ۶۵۰۰۰ عدد آدرس IP به هدر خواهد رفت.

برای حل این مشکل از مکانیسم Subnetting یا تقسیم شبکه به زیر شبکه های کوچک تر استفاده می کنیم روش کار به این صورت است که از بین بیت های قسمت Host آدرس ، با ارزش ترین بیت یا بیت ها را برداشته و از آن بیت یا بیت ها برای ایجاد Subnet های خود استفاده می کنیم…

This is an excellent tutorial for anyone wanting to pass the Microsoft, A+, or Cisco TCP/IP exam. It covers IPv4 subnetting in depth, such as how to construct the IPv4 subnet tables from the ground up.

Additional chapter includes the new IPv6 standard.

“Hi Everyone, I took my TCP/IP today with score of 948/1000, your exam preparation is excellent and good value for money. What I like about your test is the layout, dividing test into different topics, that way it is easy to spot your weak areas. I would recommend anyone out there to check your Test Prep before taking any
Microsoft Exams.” —Abdi Elmi

“I had just appeared for the TCP/IP exam, and it was quite tough. Your questions proved to be very useful additional source besides my Sybex guide. My score, 879, though I expected in 900s.” —Steven Chiu, Calcutta, India

“Passed the Microsoft TCP/IP in the mid-nineties! Glad I had your tool.” —Robert Vettor, U.S.A.

“…As for TCP/IP, I made 965 which means I missed 2 out of 58. I was positive that two of the questions had no correct answers… As for your tutorial, it is the ‘bomb’. I don’t know if you know that term means where you live, but my 15 year old daughter uses it to refer to something that is excellent. I was totally prepared and did not see anything that the tutorial did not cover in detail. Keep up the good work!” —Jim Newton, U.S.A.

“Thanks for your tutorial. You helped me pass TCP/IP and other MS Exams. Just wanted to say thanks, big time!! Thank you for your assistance in this matter.” —John Devereaux, HP Computers
