English | Size: 981.21 MB
1. Course Intro
In this video, Keith describes who this course is intended for and explains how you can use the "opt-out" features to get the most from each and every video in this course. The intro is brief, to allow you to jump right in!
2. Fun with IPv4 Basics
The largest fortress is built on a solid foundation. In this video, join Keith as you look into the basic structure of an IPv4 address. This video includes a "Test Out" feature to save you time. Let's jump in!
3. Classes, Masks, and Private IPs
IPv4 is really old, and understanding some of it quirks is critical for mastering IPv4 subnetting in today's networks. In this video, you learn how to describe an IP address as Class A, B, or C, along with identifying why it matters regarding the mask. Private IP addressing, their purpose, and ranges also are covered. Please have something ready to write on for the expert exercises you will be participating in during this video. This video includes a "Test Out" feature to save you time.
4. Beautiful Binary
In this video, you join Keith to look at some basic (and important) details regarding a Base-2 numbering system, called Binary. Please have something ready to write on for the expert exercises you will be participating in during this video. This video includes a "Test Out" feature to save you time as well.
5. Decimal to Binary Conversion
The ability to convert between the dotted decimal we configure and the binary that the computer uses is an important skill to have as we make progress toward mastering subnetting. In this video, Keith and you discuss and practice converting decimal to binary, and back again. Check out the questions at the beginning of this video to determine if you should jump to the next video or not. Expert exercises are assigned, so have your paper and writing tools ready.
6. The Mask Unveiled
The subnet Mask (also know as just "mask" by his friends) is a key to unlocking the details of the network portion, and host portion of an IPv4 address. In this video, Keith and you dive into the details of how this mask accomplishes this task. Check out the questions at the beginning of this video to determine if you can opt out, and go directly to the next video or not. Expert exercises are assigned here, so have your paper and pen (or pencil) ready.
7. Stealing Host Bits
It's the age-old story of give-and-take, and in this version we are going to "take" bits that were allocated for host addressing and give them to the network portion of the IP address. All of this is done for the purpose of creating new "sub" networks. Have some paper ready for the expert exercises in this video, and have your fingers ready for the finger game too.
8. Subnet IDs
When creating new subnetworks, you will need to know the network address for each new subnet. This video teaches you how to identify the new subnet numbers which are also known as "subnet IDs." The prerequisite for this video is the previous video titled "Stealing Host Bits."
9. Valid Host Range
The reasons for our subnets, include Hosts that will live on those networks. In this video, join Keith in learning how to identify the valid host IP addresses within a subnet that could be used by printers, routers, servers, workstations, etc. Expert exercises and opt-out questions are included in this this video, so have some paper ready!
10. Room for 1 More?
How many IP addresses are available for host addressing in your new subnets? Is it important to make sure that your subnetting plan has enough space? In this video, Keith shares with you a fast and simple way to calculate the quantity of valid host addresses for a subnet, based on the mask that is in use.
11. Reverse Engineer
Given an IP address of a host, we may need to be able to determine the subnet address that the host is connected to. In this video, Keith walks you through the four step process to do exactly that. Expert exercises and opt-out questions are both included in this video.
What do "This is a video" and "These networks are within 220.127.116.11/10" have in common?" They are both summaries. In this video, Keith describes some reasons why using IPv4 summaries are important, and then walks you through the step-by-step process on how to create them. Expert exercises and opt-out/review questions are included.
13. Wildcard Masks
For subnet masks and wildcard masks, every day is opposite day. In this video, Keith explains how wildcard masks are used, and most importantly how to create one for a given network or subnet. Expert exercises and opt-out/review questions are included.
14. Non-Octet Boundarys
In this video, Keith reinforces the methods for custom subnetting, by walking you through the subnetting process on a network that isn't using a /8, /16, or /24 mask as the starting point. Expert exercises and opt-out/review questions are included.
"Waste not, want not." Without planning, we can waste valid IPv4 host addresses on subnets that don't need them. In this video, Keith walks you through why this is real problem, and how to solve it using Variable Length Subnet Masks. This video includes an Expert Exercise and the solution is included with the NuggetLab files for this course. Opt-out questions are available at the beginning of this video.
16. Final Exam
Put your knowledge to the test with some subnetting related questions. If you've been through each of the preceding videos in this course, (and have done the expert exercises Keith has invited you to do along the way), you should be able to work through each of these questions. Thank you for viewing, and good luck!
