I just read over the Subnetting section of my Network+ book, and I must say... it is sooo confusing.

Basically all I learned is that subnetting cuts down on your usable IP addresses, they can't end in all 0's or 1's, and that's about it. Blah... I hope I don't see any subnetting questions on the test.

The teacher from my school who went over subnetting did an excellent job and spent two whole days on it.  i suggest spend some time just practicing it b/c that helped alot and do take your time b/c yes it can be confusing

I was planning on posting a Subnetting guide, but have had no time to do so. It really isn't that difficult, once it's explained properly and you do a few practice questions.

However, if you're using the Sybex book (which I believe you are), they do a horrendous job explaining it. I recommended purchasing Mike Meyer's Network+ Passport (for like $15), which does a great job breaking down the subnetting process.

I recommended buying the Passport anyways, because it is a very easy read and is perfect supplemental material to the Sybex book.

Man, Jbrown...I had no idea these links existed. Scratch the subnetting guide idea, since that area is clearly covered. Awesome stuff!

I agree that Myer's does a decent job explaining subletting. I read his book first, and then moved on to Network+ Certification Study Guide written by Glen Clarke. After reading his explanation and doing the exercises, I can do this in my sleep! Highly recommend it for subnetting

I hope other tests use subnetting more.  I spent a lot of time using it, but the practice tests I have taken so far seem to have only one or two questions about it.

They will not hit on Subnetting alot on the test. But when you enter the field you better know about it. You will use subnetting every day so get use to it and love it.

I agree Mike's book provide for a easy to remmeber work sheet that will be useable in the network

I have been through several courses and have never been able to pick up subnetting until I decided on doing the CCENT cert and bought Todd Lammle's (Sybex) book and he explains subnetting so that you can do it in your head.  Read through it and did the practice questions.  Now every subnetting question I see on the practice exams are done in about 30 seconds.

Yeah he explains how to do it in your head.  You have to memorize a table and a few other things.  I still have to write it out though.  I wonder if there's a note pad for the exam.  I think I vaguely remember that A+ exam let me use notepad.exe but I forget.

It is better to memorize the table though.  I have been writing it all out because I think it helps me memorize how to do the question but I've already memorized so many things I'm trying not to jumble things up.  I think if I focus too hard on one section I might not fit in everything else.  I'm already losing place with a couple sections in the OSI and still need to memorize the DoD model.
