Visit Site As an Instructor teaching Cisco, Comptia and CWNP courses I noticed how many people have trouble solving all kinds of binary and subnetting questions, as a result they fail at networking exams like Cisco or Microsoft because they are unable to solve these questions.
How many hosts does a certain subnet have? What is the network address? What is the broadcast address of this subnet? What is the best summary address to create?
Most people will just use a subnetting calculator to solve these kind of questions without having any clue what they are actually doing. If you do an exam…you can’t use a calculator so you have to do it yourself.
My name is René Molenaar and i’m working as a freelancer in the world of IT. Everything that has to do with Cisco, Microsoft, Linux, (Wireless) networking and security is my passion. One of the things I do in life is teaching networking (Cisco) and security courses to other IT professionals.
During my courses I notice how many people have very poor binary and subnetting skills and they fail at exams because of this. Other IT professionals I encounter need to calculate subnets or summary addresses for their networking infrastructure but have no clue how to do this…
After teaching many networking courses for years I developed my own strategy to teach binary and subnetting skills to students.
This might sound impossible to you, or maybe you think it only applies to Class C networks and not for Class B or A networks.
The truth is, you can solve any subnetting question by applying my strategy, and all from the top off your head!
I hear this all the time and to be honest with you, I’m no math guru as well! You don’t need any rocket… Read more…
