IP Subnet Math in under 15 Seconds without Calculator!

IP Subnet Math in under 15 Seconds without Calculator!

Welcome to my IP subnetting course. 

• Wouldn’t it be nice if you can do subnetting math in your head in 15 seconds or less? 

• Wouldn’t it be nice not to fret IP subnetting discussions or certification exam questions? 

• Wouldn’t it be nice not to use calculator for IP subnetting?

IP addressing math is not something any of us learnt growing up through high school and college because it is different. As a result, most IT Professionals dread at a through of dealing with IP subnetting, mask, broadcast address etc. However, many of us need to know these for our jobs or certification exam preparation such as Cisco CCNA, CompTIA, AWS, Google, and Azure Cloud Certifications, Linux certifications and many more.

In this course, I will give you quick formula to help you calculate IP subnetting related parameters in 15 seconds or less without using calculator.
