In this video, Bill Ferguson explains why your mind does not work based on binary, or even decimal, instead relying primarily on pictures. Learn how the four-step subnetting method leverages the way you remember and recall information.
- [Bill] What really makes this method…of IP subnetting different…is that it works the way your mind works.…If someone were to say, "What's six times five,"…you don't figure that out, you see it.…Somebody used some flashcards when you were a kid…or made you do your times tables.…And we call that memorizing, but what it's really doing…is making a mental imprint, a picture.…In the same way, this method will enable you…to see the IP subnets and to actually see…what a change in subnet masks…will do with the IP subnetting addresses.…
How it'll affect it.…Not only that, but because it's fun to do,…because it's fun to see, it'll stay with you…as long as you use it every once in awhile.…So instead of wanting to get away from the binary,…from the ones and zeros dancing in your head,…as quickly as possible you'll want to use this more…and understand more about how to use it quickly…to solve IP subnetting issues…in real life as well as on certification tests.…
The ability to use pictures to see IP addresses…instead of converting them to binary…
Discover how IP addresses are constructed and how to understand them better by relating them to a picture rather than converting binary numbers or memorizing charts. Learn the benefits that subnetting in your head provides in every aspect of IT networking, including routing protocols, access control lists, and network address translation. Then walk through Bill's four-step method, which leverages the rules that were used to create the original classful IP addressing schemes. Using this method, students can learn to "see" the IP addresses for each subnet. Watch the technique in action, and then practice what you've learned using the audio guides in chapter five, which provide auditory cues as you subnet in your head.
