I'm busy studying for my 70-291 exam and actually I think and it goes well except manually determine subnets without a calculator….. I just can’t find a way to do it without a scientific calculator or some kind of table – neither allowed to the exam! Can anyone help me with a step-by-step guide of how to do this.
Networks needed (subnets): 20
Max Hosts on each network: 600
IP Address to start from: 22.214.171.124 / 16 (B class)
How do I calculate the custom subnet for this + the start and end IP address of each network?
Thank you in advance,
