Most IT Engineers Can’t Subnet…here’s why…

Understanding IP Subnetting is a vital skill for every IT engineer and yet most don’t know how to do it or go about it completely the wrong way. Once you understand a few simple techniques of this subnetting tutorial, you can actually easily subnet any IP address in your head.

Does this sound familiar?

  • “I have to use a subnet calculator to work it out”
  • “I can’t pass my exams because I am too slow at subnetting”
  • “I keep failing technical interviews because I can’t subnet”
  • “I’m overwhelmed as to where to start”
  • “I worry about looking stupid at work if there is a subnetting fault on the network”

This is where Subnetting Secrets comes in. When I left the police force and went into IT I used to dread subnetting but when I was forced to write some notes to teach a class one day I stumbled across an easy way to subnet. If you can count to eight in your head then you can use my method explained in this subnetting tutorial to:

  • Learn to subnet
  • Pass exams with ease
  • Answer technical interview questions with confidence
  • Quickly troubleshoot subnetting issues at work
  • Easily work out a simple subnetting design for your office network
  • and much more…

 The techniques taught in this subnetting tutorial have been tried and tested by myself to learn to subnet,  pass my MCSE, A+, Network+, CCNA, CCNP and many other non-IT exams as well as easily  pass interviews for Cisco and BT. They have been used by many other students to effectively study for and pass their exams also. I know they will help you too.

Cisco Engineer and Internet Entrepreneur

I worked in the police in the UK for 12 years as a patrol officer and detective. While I was in the job I helped teach the new e-mail system to other officers. I took a few IT exams and then left for a career in IT in June 2000.

I took a few more exams with vendors such as Cisco and Microsoft and got a job working for Cisco for two years. I then started an IT training company teaching Cisco and computer networking courses. I built the business until it had several offices in the UK and then sold it.

I now run a publishing business and several websites teaching IT related subjects. I've learned how to build a successful company and how to make it in the world of IT. I hope what I've learned helps you too.
