It seems like there's a ton of places to practice but they all seem to do essentially the same thing. They ask a question, you put in the answer or click 'show answer'. Is there one that actually shows the calculations used or teaches you how to do it? I understand the concept of subnetting but trying to figure out an answer for 5 minutes, then getting it wrong without an explanation can be frustrating.
More than 900 practice questions and 1+ hour of video instruction.
Overview
Do you want to master subnetting? Then you need to first understand the concepts, then understand the math, and then practice the math until you internalize the math processes. This product focuses on subnetting math, giving you a tool to help you uncover your mistakes, correct them, perfect your skills, and quickly do subnetting calculations.
This product focuses on the final part of mastering subnetting: practicing the math to the point that you can do it without needing a calculator. The IP Subnetting Video and Practice Questions Kit includes more than 900 subnetting practice questionsbut it goes far beyond just a large number of questions. More importantly, it provides detailed explanations of how to find the answers to every question. It's like having a subnetting math tutor guide you through your subnetting homework sessions. The kit includes
* About 1.5 hours of videos focused on how to do the subnetting math required by the questions in this kit* More than 900 subnetting questions in both multiple-choice and fill-in-the-blank formats* A step-by-step description of how to apply the process to each specific question, which re-teaches the related subnetting process* Exams (large question sets) and quizzes (smaller question sets) that let you choose how much (or how little) time to spend in each study session* Cisco exam preparation through video advice on speed goals so you can be ready to attain Cisco CCNA certification* A testing app that includes a built-in exam timer to test your speed and accuracy
The Kit As a Supplement
The IP Subnetting Video and Practice Questions Kit supplements your learning with almost any other TCP/IP networking books, videos, or courses. Most networking learning tools include subnetting, and at its core, this product provides high-volume repetition and practice. If you sit in a Cisco Networking Academy course, are studying for Network+ or Cisco CCNA, are reading a book for study or are learning with videos, the IP Subnetting Video and Practice Questions Kit can help.
The IP Subnetting Video and Practice Questions Kit works particularly well with some other products from author Wendell Odom. The explanations of each question match the processes described in detail in these popular products:
* (Book) CCNA 200-301 Official Cert Guide, Volume 1* (Recorded Video) IP Subnetting from Beginning to Mastery: A Complete Video Course for IT Pros and Cisco CCNA Candidates* (O'Reilly Learning Live Course) IP Subnetting from Beginning to Mastery: IP Subnetting for IT Pros and Cisco CCNA Candidates
Skill Level
Beginner
What you'll learn from the videos:
* The basics of IP subnetting* The list of significant math processes related to IP subnetting* Examples of each significant math process* The user interface and content in the IP Subnetting Video and Practice Questions Kit so that you can make good use of the product* Suggestions for speed goals if you're preparing for Cisco exams
What you'll learn from the practice questions:
* Skills in performing the various subnetting math processes* A basic understanding of subnetting math, which leads to a confident mastery of subnetting math* Enough practice so that, if you put in the work, you can learn to perform subnetting math quickly
Who Should Take This Course
* IT and networking professionals who want to fully understand subnetting by mastering the math processes, even to the point of doing the math without a calculator regularly in their jobs* Network certification candidates (Cisco CCNA, CCNP, CompTIA Network+, and so on) who need to be ready to do the math, with no calculator and no reference information, at speed, at least for exam day
Course Requirements
Anyone using this product should already know something about subnetting. While it is possible to use these practice questions to learn the math, this product is meant to be a supplemental tool. For instance, anyone who has read a CCNA certification guide or a general TCP/IP book that discusses subnetting math should have enough background to make good use of this product.

Look at how a Class B network can be subnetted. If you have network 172.16.0.0, then you know that its natural mask is 255.255.0.0 or 172.16.0.0/16. Extending the mask to anything beyond 255.255.0.0 means you are subnetting. You can quickly see that you have the ability to create a lot more subnets than with the Class C network. If you use a mask of 255.255.248.0 (/21), how many subnets and hosts per subnet does this allow for?
You use five bits from the original host bits for subnets. This allows you to have 32 subnets (25). When the five bits for subnetting are used, you are left with 11 bits for host addresses. This allows each subnet so have 2048 host addresses (211), 2046 of which could be assigned to devices.
Now that you understand subnetting, put this knowledge to use. In this example, you are given two address / mask combinations, written with the prefix/length notation, which have been assigned to two devices. Your task is to determine if these devices are on the same subnet or different subnets. You can use the address and mask of each device in order to determine to which subnet each address belongs.
In all of the previous examples of subnetting, notice that the same subnet mask was applied for all the subnets. This means that each subnet has the same number of available host addresses. You need this in some cases, but, in most cases when there is the same subnet mask for all subnets, it wastes address space. For example, in the Sample Exercise 2 section, a class C network was split into eight equal-size subnets; however, each subnet did not utilize all available host addresses, which resulted in wasted address space. Figure 4 illustrates this wasted address space.
I'm having a difficult time trying to find any information on subnetting a v6 address into smaller subnets. A coworker is studying for an MS exam and they had a question on there that frankly makes no sense. The subnet calculators that I'm using doesn't give the same answer either. I'm going to put the question and answer in here, but I'd like to know how to subnet this out manually if possible:
So, if we use a given address with a higher Subnet Mask value like given in the second example, we will have more networks. In other words, we can divide the network into smaller pieces. So, we will not waste the IP Addresses. Smaller networks that has few hosts do not need more addresses. With Subnetting, using a small network with few host addresses is a way of best practice of a network engineer.
Therefore, subnetting practice is very much required when preparing for the CCNA exam. To clear the exam, passing marks of 825 out of 1000 are needed which becomes even more difficult to score when we have a stringent time limit that we are given. So, you need to have a thorough understanding of subnetting to finish your exam in time. Hence, I advice you to prepare well for this topic because it is the most time consuming part of the exam especially if you are slow at calculations.
The second part of the question was, what is the subnet mask, /26, in dotted decimal? The way to do this when you're first learning subnetting is to write out the bit pattern at the top of a piece of paper.
When working on a subnetting question, you only need to write out the octet that the subnetting is happening on. Because the other octets will always be unchanged, you don't have to write out the whole IP address in full every time.
I recommend you don't spend hours practicing subnetting in one sitting, that's no fun for anybody. To get ready for the exam, you can just pick your favourite practice site and spend five or 10 minutes a day working through a few problems.
If you do that for days or even weeks before the exam, you'll be fine when you get those subnetting questions. Another thing to tell you is that in the real world, people don't do subnetting in their head (if that wasn't obvious already). be457b7860
