I have been using Mike Meyers AIO as well as Labsim. Everything has been going smoothly until I ran into subnetting yesterday. I cannot seem to grasp it at all, no matter how much I read and watch, it just does not make sense to me. Could anyone point me in the right direction or lend some advice? Thanks.
Here are some great practice sites:
subnettingquestions.com - Free Subnetting Questions and Answers Randomly Generated Online
IP Subnet Practice
I didn't use this site but many people recommend it: Learn To Subnet: A Free, Lecture-Based Presentation on IP Addressing and Subnetting
getting different explanations from different sources help: watch the professor messer videos on subnetting. There is one on binary math and two on subnetting Professor Messer's Free CompTIA Network+ Certification Training Course | Professor Messer - CompTIA A+, CompTIA Network+, Certification Training
cisco has some games that may help you. There is a binary math game and a couple different subnetting games. You will probably have to sign up for a free account. https://learningnetwork.cisco.com/docs/DOC-1802
Cisco Binary Game
After you have ANDing down and really understand the concepts and can do the problems with binary math I recommend using one of the charts or other methods out there to gain speed. I took this guys method and changed it around a bit to work better for me. Creating Your Own Mental Subnet Calculator
I would say you need to have a pretty good handle on it. You need to be able to subnet but not necessarily lightning fast. Of course there's only so much I can say due to the NDA and you might get totally different questions than I did. Depending on how you are doing with the other objectives- I think there's still plenty of time before the end of the year to learn it well enough for the Net+.
Is it just a general head scratcher for you right now or do you have some specific questions?
If you just ran into yesterday, reread that section on Subnetting again a couple more times. I don't think anyone can fully grasp it the first time. You don't need to be an expert on it either but it will be important if you plan to go beyond Network+. A full basic understanding is the very minimal that you need, but read into it a little more just in case. We all had different experiences so can't say exactly.

Thanks you for this. This is so much easier to take in than the other methods I have looked at.
Those questions are a bit too advanced for the Net+, but you will need to understand sub-netting to that extent for CCNA etc.
